Unanswered Futures Questions

BTC community, I am almost a whole coiner. I firmly believe in this revolutionary power as the key to freedom from economic tyranny, however, there have been questions that have not truly been answered. Basically, futures/derivatives can and will kill Bitcoin if it becomes a bigger threat to the Central Banks than it already is. (I’m not here to attack Bitcoin, I just want answers.)

The only rebuttals to this price suppression argument have been:

1. “If Bitcoin jumps 20% or more, then all those futures contracts get wiped.” - Bitcoin University. My question is, this only works assuming a positive jump of Bitcoin. However, if the price is being suppressed and continues to be suppressed, why would anyone buy BTC to make it jump 20% or more in the first place. Also, money is unlimited to Central Banks and assuming the small market cap of BTC, it should be fairly easy.
2. “Banks will inevitably be unable to keep printing more and more money to suppress the price of Bitcoin. It will soon end in disaster.” - Swan Bitcoin The Gold Market Cap of (11.4T) is substantially bigger than BTC Market Cap of (500B). Gold futures manipulation has been continuing for decades just from Private Banks. If Central Banks became involved wouldn’t it be game over. Who is to say that Central Banks and united governments are not already suppressing the BTC price to discourage adoption. This ‘it will eventually fail’ rebuttal is not really an argument from Swan. It’s just a hope that eventually people will wake up and ‘turn away from the system.’
3. “Acc. to Game Theory any rational nation/bank would instead adopt Bitcoin”. - Swan Bitcoin. Why would any rational nation or bank purposefully adopt a poison that would weaken its power. Instead, wouldn’t the argument be that ‘all rational banks/nations would work collectively to suppress the price of Bitcoin to discourage adoption.’ Which is what could be happening right now.

Most rebuttals to Willy Woo have ultimately just been ‘they can’t print money forever’ or ‘bitcoin is different from gold, it can’t happen to BTC’. If someone could either point out things I overlooked or explain them better that would be great.
