Nice research, would like hearing your thoughts on how to improve HBD.
Hypothetically speaking, if government wanted to take over PoS they could go for the stakeholders before initiating additional inflation to buy some. Ok ok, it depends how much eth stakeholders the state has, but i assume every country has a few whales and a bunch of smaller stakeholders to take from. But it all has the price and it's likely that such action would lead towards political suicide or possible civil outrage.
It makes no sense to attack the network (from the perapective of state), it's easier to simply restrict and track the usage of crypto wallets.
