> I understand the sentiment, but.. do you realize how much more expensive that would make all these services?

It wouldn't. For example, before Gmail, email was often free or nearly free (bundled with your internet service), but in most cases, you could talk to a human if you had issues with the service.

What we couldn't do is turn these business models into planetary-scale behemoths that rake in hundreds of billions of dollars in revenue. In essence, you couldn't have Google or Facebook with good customer support. I'm not here to argue that Google or Facebook are a net negative, but the trade-offs here are different from what you describe.
