I have gone through many county clerk & recorder documents. I regularly see 6 and 7 figure houses change hands via recorded quit claim that says things like: 'love and other valuable consideration' or the frequent 'ten dollars'.
And I have read a lot of State law. While there is shady stuff in law such as "federal IRS lien can be recorded without a hearing nor judgment in State court", I have yet to see law which requires $ to exchange a house. Am interested in seeing a State law reference you may know of.
There was another post here about a thought experiment where someone asked if I had eight billion dollars, how can I send a dollar to every person on earth? Well, right now you can't because it costs too much to send or receive money.
I don't have a solution but the fact that eth is full of "gas" people who want USD, makes me think it is no different from the Bitcoin crowd regardless of the pos switch. Or to quote the wolf of wall street, the people who own Bitcoin and Ethereum networks still take home cold hard cash. Don't fall for their BS. Bitcoin or eth doesn't pay for your mining rigs or your electricity.
