Short answer: They do not.
Long answer:
There are different people posting here. Those with less than 10 posts and asking such thing are usually French or Germans that once read in a newspaper about the big companies not paying taxes, "stealing money from them." Then, they think as they make 50k and pay 35% taxed, they can do so too. Long story short, it does not work as long as they do not︀ move away form the EU.
Then, there are the people like OP, which are long︁ gong and live in airports, hotels and the like. In this case, the question actually︂ does make sense, up to a certain extent. I personally would recommend him SG or︃ GG, it will cost about 5k per year.
And finally, there are those mentioned earlier︄ that have substantial income and the possibilities to play the rule by the game. They︅ hire 2 guys somewhere and have substance. This certainly works for now, I suspect that︆ there soon will be a company on Taobao offering such substance as a service and︇ soon, the rules will change again. Also, the corrput governments have too many corrupt and︈ lazy officials that are never personally liable for their lousy work. Hence, their laws are︉ full of loopholes. Of course, the governments are in need to fill some covid spending︊ debts and are now looking for an easier way to get money than by covering︋ loopholes. Hence, they introduced the tax evasion laws where any structure to avoid tax is︌ per se subject to the avoided tax, even if legal. Of course, this also does︍ not change much as all it does it increase the lawyers fees as they have︎ to find excuses for the structure in order to qualify as legitimate.
