How is investing in something that people need being a slave, but investing in something no one needs being free? If I invest in dollars I hold something that masses of people need for paying off debt owed to banks. I am the master, not the slave. On the other hand, if you traded dollars for Bitcoin you are the slave because you need other people to invest and buy your Bitcoin otherwise you cannot get your dollars back. It's hilarious how you Bitcoin evangelists think that you're the masters while in reality you're the slaves.
Actually in this case you are talking at the same time saying that you yourself are also a slave in the end because if you consider that investing in bitcoin requires other people to buy bitcoin that we have in the end but at least we can have freedom of control of the bitcoin that we have. But in contrast to your belief where you entrust your dollars to the government then indirectly the concept becomes the same that you are also a slave and worse you are also pressured by the government which does limit you with a centralized scheme owned by the bank.When you say people who are in bitcoin become slaves then what are you now buddy?
I think for now all you have to do is go back to your respective beliefs, if indeed you believe what you believe in at least you don't judge that other people are wrong because it will show your own stupidity that only wants to be justified by others but you don't respect others properly.
