Bitcoin mixers and boating accidents aside....
Discussion
Unfortunately I think those approaches are security theatre
We're seeing the fiat rails close for CoinJoined bitcoin and the mixer crackdowns (Bitcoin Fog) are likely to continue
I started a project to simplify access to mining (Rigly) so people can get new bitcoin that way
But there just isn't much new bitcoin left...
I kind of agree with you to a large extent. I think our main hope then would have to be mass adoption, where the state has very little option other than just accept the status quo. I'm not from the US, obviously but your government has quite a large holding as I understand it. Maybe they'll see the light one day!
And you're right, there's certainly a dwindling supply, more so after the halving.
