In my opinion, the value isn't always about USD, but more on what we can buy or do something with Bitcoin. Like, if the price is $6K and we can just buy one thing then when the price is $12k, we can buy two things. Why wouldn't I hope the price is $12k?

Basically, people understand that one bitcoin worth of one bitcoin but that's gonna be useless if we don't use it (to pay, buy, or speculate) and that's why people are debating.
