You say PoS is an oligarchy, but it still offers anyone to participate in markets they previously were unable to.

Overall, regulation is slow! But it’s getting there. I don’t think crpyto will solve all of.humans problems, but I might just help with some. It’s going to be interesting seeing how it all plays out - people thought it was going to be here and gone in a year, but it’s been over a decade now.
Banging whenever you want without worry about child support? That sounds like the woke agenda
