That is a major advantage that makes bitcoin the coin for investors who like being independent. Being decentralized makes it not to be anybody's business, currency or point of regulation. Obama, Trump, Biden and who next? won't have control over it bupt they can make hate speech like Warren buffet 
At any point in life we still need people in our space. The axiom "A tree doesn't make a forest" lays credence to this fact. The above people you mentioned can still speed up or delay the progress of Bitcoin despite it being a decentralized crypto. It's the same way its progress has been delayed so far because Trump bashed it. Imagine if Trump supported it, don't you think a lot of people (billionaires inclusive) would've keyed in and bought? A community crypto needs people to grow and Bitcoin is one. However, I don't think Biden will want to promote Bitcoin. He would rather play safe except he is beaten into it by the crowd because he seems someone who will want to dance to the tune of the crowd. Biden looks more like a puppet to me than a real deal.
