Everything you mentioned are related to privacy and decentralization, people don't care with that, as long as Trump talk about Bitcoin and do something that looks like he support Bitcoin even it makes Bitcoin become more centralized, people will call it a win.
Similar like your first question, I'd like to know what Trump will do to both Keonne Rodriguez and William Lonergan Hill (Samourai wallet's developers).
This is something that many members of the forum have missed. As far as I can see, only forum members and bitcoin maximalists care about bitcoin's privacy and decentralization. The rest of the market, they hardly care about these things, the only thing they care about is how to increase the value of their portfolio and how to maximize profits. That's why people support Trump, they don't care what Trump will do with Bitcoin as long as its price can rise and they make a profit.
Trump knows that so he doesn't even need to fulfill all his promises, just bitcoin price increases and everyone profits. The market will quickly forget all his promises and even praise him.
