Earlier quoted context omitted.
Sure but a court can order you to do a future transaction that effectively reverses the original. (Akin to how almost every single reversed transaction _actually_ works). And if you refuse, they can order your local (or not so local) PD to jail you until you comply. Blockchain still exists in the real world with its very real rules.
Well, of course... but if they're relying on court orders how is exactly blockchain technology helping in this process?
If it was done with wire transfers and etc they'd have to do many requests to learn what transfers existed while with bitcoin all transactions are public so its just faster. Imagine having to walk down to the local PD every time to approve your web search vs just doing them without that.
