Oh wait I forgot the drivechain use case is "it will make shitcoins obsolete".

No it won't. It is willfully ignorant to assert that shitcoins exist, entirely because sidechains on bitcoin don't. Firstly, sidechains already exist, and nobody fucking uses them. Secondly, shitcoin projects are not noble science experiments -- they are venal cash grabs, and as long as stupid people will exist, so will venal cast grabs.
