So you replaced "shareholders" with "developers of cryptocurrencies/beneficiaries of the development fund".
Does a rose, by any other name, not smell as sweet? I mean, from the case you're making, these v3 protocols seem more like securities.
Stablecoins sound exactly like banks. Which means AML/KYC/Reserves on the horizon.
The entire cryptocurrency space recreated the current financial system, rooked in a new generation of suckers (and some old one's that should have known better), did everything current financial product regulations were put in place to prevent, made it as energy inefficient as humanly possible in the case of PoW, but it isn't all that cause it's called something different.
My distinction without a difference alarm is ringing itself off the wall at the moment.
