it's a dogwhistle for likeminded folx

Capitalism is not just "the existence of money and markets". You can still have money and markets without capitalism.

Capitalism is when businesses do things I don't like, and the more they do those things the more capitalist it is.

> You can still have money and markets without capitalism

Money yes markets ish. A pillar of capitalism is the private ownership of capital, without private ownership many markets no longer exist (talking the economic definition of 'market').

"Some markets become obsolete when you remove capitalism" is not the same as "markets are only a thing under capitalism".

The real estate market would probably look much different and may even dissolve entirely if you forbid private ownership of real estate capital. I don't think this is a groundbreaking insight, I'm just clarifying for those who are careless about their use of words.

Yes but there's also people who think capitalism = things they don't like and don't bother to think about what the alternative truly looks like.

Straw men are not coming for your privately-owned home any time soon, friend.

Capitalism can also mean that politics shouldn't intervene when monopolies dominate markets. Then markets may also disappear in capitalism.

That's not what capitalism means. That's corporatism, if anything, assuming (as a sensible default) that corporations are the ones holding monopolies.

This is technically true in the abstract, but the people who use phrases like "post-capitalist" usually have a slightly different meaning in mind than what you described.

Don't know if there is such a word but there's definitely an HN guideline about not-writing shallow reaction comments about such triggers.
