If you don't have 51% of the mining capacity, the network, the network is secure. NOBODY will have 51%, it would cost billions. Also, it would be fruitless, absolute control of the network would mean zero confidence in it, thus, no value in #BTC.

The danger of censorship is real way before 51%
It absolutely fucking is. Governments are cunts. You specified mining though, there's little they can do about that. They can regulate it, of course, but miners will just move their rigs!
The big mega miners can’t move though.. they’re publicly traded, govt-regulated companies. Their shareholders will require them to comply.
I even with 51% or more its not worth destroying the aaset you are stealing lol
