The irony, of course, is that the only thing they're a "victim" of is those same politicians.
The initial ban in Sweden was itself legislated in 1999 when the Riksdag became majority women.
The libertarian and market-driven framing is a uniquely American and Canadian lens that doesn't hold much water in much of Europe - especially highly collectivist and monocultural societies like much of Scandinavia. It's the same with attitudes around drug legalization (zero-tolerance but with a heavy rehabilitation tilt is the mainstream view in much of Europe).

I wouldn't underestimate that market. While men seem to consume more porn, "men" also includes "gay men" of course, who won't be quite as interested in seeing naked women even if we pretend women aren't interested in sex.
Plus, women may only be about a half as interested in pornography as men (according to https://www.pornhub.com/insights/2024-year-in-review 38% of visitors were female), the market sure seems large enough.
There are definitely market differences (the pay gap for male actors, for instance, and of course the double standard that judges women more than men for consuming such content) but the divide is not even close to absolute.
Your post ("it is extremely unlikely that someone in the sex industry is Swedish/Norwegian/Icelandic/Danish given the mixture of social bias and social safety net") supposes that women go into the sex industry out of desperation, but that's not true. Some people are fine with selling their bodies, to various degrees, and don't have a problem making an income that way.
