What do you actually know about soviet housing? I've done significant academic research on the topic. It's not just a simple "they built a certain type of building". The reason they all look so similar is that their construction method was pre-fab concrete panels. It was a revolutionary technology at the time, and allowed them to solve their housing crisis. They were called "Khrushchyovka" after whom you can guess. He made it his mission to solve the Soviet Housing crisis when he took over and was largely successful.

You have to keep in mind the historical context. The people moving into these buildings were coming from a pre-industrial society where they commonly had so electricity, dirt floors, and no insulation. These were a significant upgrade from the pre-USSR constructions. They started construction in the 1940s, and really took off in the 50s.

I think the main takeaways from them shouldn't be "We should build these exact things". and I don't think that's what people who support them are advocating for. I think what they are trying to point out is that if you standardize production, and use economies of scale, it is entirely possible to build tons of housing quickly and cheaply. And considering the way housing prices look these days I'd expect that to be an idea anyone can get behind.
