That just makes the price and volume much easier to manipulate by these handful of centralized exchanges and frontrun normal users before their government takes it's turn in censoring/stealing/surveilling them. 

Users can do what they want. I'm just pointing out it makes zero sense to use Bitcoin that way. It's the worst of Bitcoin and the worst of fiat with none of the benefits of either.

Has nothing to do with being puritan (ironically a bitcoin maxi is calling others puritans, which I am not) it's about larping like these centralized, custodial, white market transactions are Bitcoin or have any relevance to it's core value prop.

Monero is already plenty adopted on the only markets that matter for Bitcoins value prop
