One of the main points of Mag World is that different orders of magnitude are qualitatively different. Yes, of course, with more assets you can get more credit. But the types of credit are so different as to be incomparable. At ^2 wealth, without greater wealth around you, you probably can only get a usurious payday loan. At ^5 wealth you can take out a HELOC against property you hold title to. At ^10 wealth, a person can apparently buy and control a social media platform, without even "spending" any of their own money!

As they say, quantity has a quality all of its own.
