If you're a government considering whether it's worth ripping up IP rules, I think two of your questions are how long before the US comes back with another trade deal you want and what will the US do to you to retaliate for you ripping up IP rules. (There will be retaliation. Look at the US today and tell me there won't be retaliation for everything.)
That's why I think the US has to be basically gone for good before this is realistic.
