You are right these days everyone only cares about wanting to see the 100K that is being talked about everywhere. I don't think that is bad but back to the goal and the things Satoshi stood for are now being pushed in the opposite direction as government agencies, corporations, etc try to control the remaining bitcoin. What does 100K mean if we lose the essence of Bitcoin.
As you think, do you think people really need decentralization and privacy like they say? Or are they only concerned with their own wealth? and what does privacy mean to the poor? We should be realistic that in today's life, money and wealth are the most important, only money can help you maintain life and survive, privacy will not feed you.
Also, as I said earlier, the price we pay for bitcoin to become popular is government intervention and regulation, which is inevitable because after all, they are the ones who control this world. Whether we like it or not, no one can stop the US government if they want to buy a majority of bitcoin and turn it into a national reserve. If we can't do anything to stop it, then why should we care? Instead, we should care about our own interests before it's too late.
I think people are really having a misconception here when they assume that the government will eventually take control of Bitcoin if they (the government) buy very large bitcoins. The only influence the government can have on bitcoin is the area of bitcoin price, aside this, the government would have to have a kind of influence on the of miners, the developers, including bitcoin users all over the world before we can really say the government has a total control over Bitcoin. The decentralized nature of bitcoin won't even allow that to happen.
You are right, we cannot stop the government from buying bitcoins, we can’t stop them from having a bitcoin reserve and we cannot also stop the government from doing their job which is 'regulation'. Rather than focus more on what the government intends to do with the bitcoins they would buy, we should focus more on creating strategies for ourselves that will help us achieve our bitcoin goals even in the midst of government actions and regulations.
