The real issue is the fundamental ways in which ownership is constructed in modern society. The "Eth bros", the entire VC world, essentially relies on the State to validate ownership. Thus there is a fundamental conflict between an entity or corporation that "owns itself" on the Blockchain and an actual (real-world) company that could have shareholders, investors, owners, & etc in the meat-world.

So this is a situation where one system must dominate; either the Fiat or the Blockchain. Your traditional wealth, your Big houses, your Lambos, all require Fiat to ultimately be the "value base layer."
