Not just that, Nordic sex workers have a combination of problems in the various countries, like not being able to rent private housing because that’s seen as profiting off sex workers (pimping) and various other ancillary limitations surrounding that.
You’re better off fully decriminalizing first, and then later probably creating some sort of government sanctioned organization made up of sex workers and customers, to regulate the industry.
Allow me to gas Finland up a bit more. They’re higher than Germany in terms of innovation (triadic patents per capita), they have semi-democratically owned grocery stores with 90% of the country being a member/co-owner, they have 60% union density and a Ghent system (like Sweden, unlike Norway), their housing prices were among the few in Europe falling - after the government started their Housing First initiative and built social housing for the poor, their education system being so good (despite being relaxed unlike e.g. Singapore) and state-funded instead of private… life is pretty good in Finland.
