Lemme know when they successfully ban The Pirate Bay. you know the one, that just keeps coming back.
It's not really the same thing, and it's not about banning your ability to send Bitcoin from one address to the other or from one person/country/continent to a different one. When thepiratebay.org goes down and if all their mirror sites go down, they are gone until someone brings them online again. You can't bring down Bitcoin in that way because there is no reliance on a single site/service/wallet etc. The way to take out Bitcoin is by attacking the technology and infrastructure that secures it, confirms your transactions, and generates new blocks. They might not go to those lengths, but it's the best way to achieve your sinister plans.
A coordinated confiscation of hundreds of thousands of ASICs is not something you can easily replace just like that. They are not jars of water that you simply fill up and put in place of the old ones. Even that would take some time. Those ASICs need to be manufactured first to replace the old ones.
It was Malaysia, but the equipment was seized due to being run on stolen electricity, not because they banned mining
Still, they wanted to send a strong signal by doing that. Seized goods can be auctioned off unless it's something illegal like drugs. The Malaysian government used the steamrollers as symbolism of what they think of the industry. Personal opinion, of course.
