Because one of the constantly shifting goal posts that the crypto community used a lot in the past is "payment method without third parties". So it is relevant to compare to Visa, to establish that Bitcoin utterly sucks in that regard, without 2nd, 3rd etc. layer solutions.

There is a lot of accusations of "straw manning" when people calmly point out that except as a gamble and to enable relatively small amount of criminal transactions, Bitcoin has as of now failed to do in anything of the many things its true believers want it to achieve.

I have actually been following the crypto space since the cypherpunk days (by reading archives early on because I'm too young to have been around since the true start) and without regret (okay, a little bit of regret :-) missed out on large gains by selling all my crypto early on. One of the more interesting projects https://en.wikipedia.org/wiki/GNU_Taler doesn't get enough hype because it doesn't make claims that make you feel like a badass outlaw, sticking it to the man and potentially avoiding taxes. I still hope it takes off because it would be an actual digital cash, privacy preserving while still allowing for societal important things like taxes to work.

It's already successful. First of all: simply by enabling new methods of civil disobedience and eliminating future opportunities for government overreach it is already working to strengthen our democracy. Second, people are actually using it today to escape oppressive currency controls in certain places like Argentina. And there is real potential for Bitcoin to act as an inflation hedge that is much more convenient than gold (we have yet to see the long-term price behaviour).
