On the face of it, yes. But does it really?

Perhaps if Trump was pro bitcoin. But is he? Who knows? He loved Wikileaks before he was elected. Then after, he had Assange thrown in the torture dungeon for about 5 years.

So I suppose your argument would hold true if Trump does what he says he will do. But he is a politician...

Even if he does allow self custody doesn't mean he wouldn't make registering the withdrawal addresses compulsory and transferring from those addresses illegal. 

Perhaps the only thing to do is vote for Trump, hope for the best, and expect the worst?
