>You state this as fact, but the anthropological consensus doesn't agree with this.

Yes it does. This is anthropology 101. In hunter gatherer societies wealth doesn't really exist. People eat and get resources off the land without ever really accumulating wealth. For civilization to form, first wealth must evolve into a form where it is abundant, identical and useable like coins.

So like grain when extremely abundant naturally maps into something like coins where people instead of bartering can "pay" others with grain and save up on grain. If humans begin farming and then grain becomes very abundant in society, something changes.

It then becomes possible for the accumulation of resources by a central source as in one person owns more grain than another person. Wealth inequality so to say. When one person is much more wealthy than another, this allows him to gain a sort of artificial power over others by employing others and paying them a salary. This CAN only exist if some static countable resource exists that can function in place of a monetary denomination.

This is ultimately what causes people to coordinate. No amount of leadership or charisma is going to herd humans into a organized team of hundreds to build projects as complex as a boeing 747. You HAVE to pay people for this to happen. You have to offer them something that benefits them that's more then just your charisma.

These are the projects that define civilization.

This is IN FACT the anthropological consensus on how civilization forms in academia. I'm not making this up. Go read up on it, this is how they believe advanced civilization formed in some places and didn't in others. So places that are really tropical tend not to form advance civilization because things like grain rot. This prevents anyone from accumulating resources which prevents wealth inequality which prevents a single individual coordinating other individuals to create the public works that define modern civilization as we know it.

>Early hunter gatherer societies are thought to have been communal, with no notion of property. It's not "human nature".

You're describing tribes and hunter and gatherers. I'm describing civilization. The next step. Mesopotamia. The progression from tribes and cavemen to civilization involves the steps I describe above.

Also I'm not calling "civilization" natural. Nothing of the sort. The times we live in are not natural at all. Modern civilization is NOT natural. But. Capitalism, wealth inequality and business DOES form the basis of civilization as we know it. In short, IP is fundamental to civilization, but it is not necessarily natural. I am more appealing to whether you value the idea of civilization itself, and less to whether something is compatible to human nature in its earliest form as these are two orthogonal concepts.

>This is an ideological argument, which is fine, but nothing anywhere close to "the truth", and especially, not the only or best way to organize things.

Ideological my ass, there's barely any evidence of complex projects forming out of pure communal goodwill. The only time I've seen people do something like this of equal complexity out in the wild is Linux. And it only happened because Linux is uniquely a software project which is very cheap to develop for. And EVEN then open source developers for linux need corporate jobs in order to get paid a living wage so that they can afford to have spare time working on a charity project like Linux. Linux exists because developer time working on Linux is paid for by FOR-profit corporations.

>You want to have this argument, fine, but you'll have to step down from the teaching desk and accept your belief is not universal.

It's not a belief. That's what you're missing. The logic composes into a singular conclusion. I'm right. You may not agree with me now and that's just part of human nature. Maybe think about it for a couple months and eventually you may hit the realization that your idea of how the world works was a little off. Yeah I know I'm an asshole for sort of bluntly burying everyone I see with the brutal truth, but think about it for a bit.

>By actually manufacturing and selling aircrafts to airlines? 747s are not infinitely copyable. Discussion has now shifted from ideas to tangible objects.

The raw materials used to create a boeing 747 are not rare at all. They are easily accessible. The aggregate value of material cost of a 747 is significantly less than the actual value of the 747 itself meaning that much of the worth of the 747 is in the crystallization of the idea of what a 747 is. The 747 is at it's core an idea, that's what separates it from just being a just a mishmash of random materials. It is at it's core an IP.

Yes it's not infinitely copyable so it doesn't suffer from the ill effects of software. But they are one in the same, it's just that the 747 has additional protections of the "idea" being encrypted into the plane itself and the people who make the plane. Software the idea is fully crystallized into a single place: the source code and it suffers from being easily copied.

This is where IP law comes from. The idea of a 747 is by nature not easily copied, so people didn't need to instantiate the concept of IP because by default it's just harder to copy. IP was invented because of the distinction between ideas that are easily copied and not easily copied. People wanted to bring the properties of the 747 to software.

>Remains to be seen. There should be no functional difference between raising hundreds of millions from venture capitalists or crowdfunding. We just need to find ways to raise these platforms to the billion dollar scale.

I think we're in agreement. We agree on the benefits and downsides of IP. You just think that altruism could function just as well as the incentives created by IP and it seems you're clear that there is currently no evidence to support your hypothesis other than a smattering of freak anomalies like Linux. Whether that evidence will materialize in the future remains to be seen.
