Uhh, OP learned how barter and fiat money works? That's cute, at least people now knows about the basics of how we put value on something base on trust. My point is that OP, you are saying that bitcoin was valued on how we deem it's value is but you forgot the fact that that's how almost anything precious has been traded a long time ago.
Trust wont really be that enough since there are lots of criteria's need to be considered first before a certain thing would be having value and imagine on how monetary system had started from
those old days comparing to now which it starts out to be a barter system until those coins or money had been the start.Its a common concept and as we do go ahead or
technology do enhanced then its just normal that we do upgrade as well in terms of financial system.
