I would never describe myself as a "capitalist" but I do kinda understand the structure and function of markets a little bit, and it's sometimes frustrating chatting with leftists whose entire experience of markets has been watching the enormous trash-fire of post-2008 dysfunctional crime-based capitalism destroy the possibility of them ever owning a home. Like if you really liked trains but lived in a town where 3/4 of the population had been killed by a chemical supply train derailment
@glyph markets work pretty well as long as there's no monopolies. Which means they maybe can't work in "natural monopoly" settings like roads and utilities, sure. Regulating them is essential to prevent monopolies, but then you need to be careful to avoid creating perverse incentives. So yeah, they're a tool, with caveats. I'm still on the fence about abstract/indirect markets like stock markets and derivates markets, they serve some functions but it would be nice to explore alternatives!
