As the saying goes: markets can stay irrational longer than you can stay liquid. Most people will probably just use other means to move value if Bitcoin becomes unusable for a few decades. > hide the traffic of your mining operations through tor or a vpn. I'm not talking about censoring pool internet traffic. Rather to reactively reorg "bad" blocks. The mere thread of that should cause most rational actors to self-censor. Even if you offer 10x the block subsidy in fees for a single transaction the US government can easily afford reorging them all and wasting your money. But as I said above, at those prices that are cheaper ways to move value.
