While rent control isn’t a solution, I don’t think it’s ever intended to be one

The rhetoric I see around it paints it as a solution, and there are people who say with full sincerity that supply and demand is capitalist propaganda.

renoviction, the act of using a renovation as an excuse to evict people and charge more for the same thing

This whole dynamic is only surface level. The excuse doesn't matter; if the whole market can get those prices, it's because of the number/means of people seeking housing vs the supply. It will happen with or without an excuse to smooth things over. There are plenty of very run-down places in high demand low supply areas that cost huge amounts without any such aesthetic justification.

I don’t think rent control would prevent development of new housing either, as landlords aren’t the only folks who buy properties, even though it’s almost financially impossible to buy a house in certain inflated markets these days no matter who you are.

It demonstrably has prevented and does prevent the development of new housing, among other market distortions, and afaik this is one of the few things economists broadly agree on. To your point, maybe it would be possible that over time, eventually, all rental apartments would be converted into condos etc. as a market response to rent control. But given the demand specifically for rentals (for which there is then artificially reduced incentive to meet), and the difficulty you mention for most people actually buying a home outright, it's easy to see why in practice there will be an extended, possibly indefinite, period where housing supply will be suppressed by the policy. One reason it could end up indefinite is that homeowners as a voting class have an incentive to protect the value of their properties, and that often means passing regulations that in practice constrain housing supply. When most voters are renters, this is less of a problem.

The way I see it, looking at housing markets as being "inflated", as if the prices were the result of some trick of greedly landlords, is completely wrong and missing the bigger picture. Real estate is a wealth asset, a store of wealth, and all of those are skyrocketing in dollar terms beyond official measures of inflation, as part of a process of wealth being transferred away from the majority of the population and the value/negotiating power of labor declining. If people only look at their personal situations and false ideas of what prices "should" be and what is subjectively "fair", they miss this bigger picture and overlook solutions that could actually work.

Which, in the case of housing, is more housing.
