Considering the law is now official I spoke to different attorneys out of curiosity.
It seems that setting up a company is sufficient for a residence permit and that the process is straightforward to go through. However, I do think it is important to choose your lawyer and accountant carefully, as this seems to me to be one of the countries where this could cause trouble if you don't. And by trouble I mean it can become a pain in the ass to wait and you're stuck.
I think it currently makes Turkey one of the most accessible and attractive options if you only want to pay 0% tax. Most other countries and set-ups require a hefty investment.
The only thing I haven't figured out yet is banking, how difficult it is to open an (EMI) account, and whether there are any bans on holding foreign currency (given the massive inflation). When I spent time in Turkey myself, I noticed that many parties maintained a Payoneer account. The Turkish economy is not doing too great.
If anyone has any info and knows more, that would be very welcome.
