The situation in Germany is dire but they do not have decriminalisation there. Their system is legalisation. Legalisation seems to work better in the Netherlands, but in New Zealand they have decriminalisation.
In New Zealand if two or three women choose to work together as prostitutes from the same flat or house they will not be arrested. In Germany they probably have to get permission and if not they will be punished.
Your ideal is no prostitution, which we know the Nordic model has not achieved in any of the countries where it has been applied. Far from it.
I look at it differently. I think if prostitution is going to exist, what would be the best form? The best form would be women working together, keeping the profits for themselves and making the rules for themselves.
There is a blog by a prostitute in New Zealand where she said that brothels have been closing down there. She doesn't mean the SOOBs (Small Owner-Operated Brothels), she means the traditional brothel run by a pimp or madam. They still have problems there but the government says that prostitution has not increased. A few have disputed this.
People who believe in decriminalisation don't usually use the word 'empowering'. It is an ambiguous word. However, if a Chinese woman comes to Britain and returns to China with tens of thousand of pounds and sets up her own businesses, then 'empowering' would seem to be a good word for it.
In Sweden they set great store on what they call 'normalisation'. More Swedish people accept the Nordic model. The proportion of people who accept it fluctuates but more people accept that men should be punished for paying for sex. Even though they don't believe it will work at reducing demand. Also, it's not really the Nordic model they seem to want because they think prostitutes should be punished too. So it looks like they want the American model. In any case, want they want has been moulded by the lies their government has told them.
