I can confirm from personal and real experience that what you tell is true. In Europe you will always be taxed SOMEWHERE, no matter where you go or how long you stay somewhere. For each possible scenario there is a taxation rule.
In Europe the rule is that if you don't stay anywhere for 183 days, you will be taxed in the country from which you have your nationality. Maybe if you become stateless it might work, but that will cause a lot of other problems. I have somewhere the text but am too lazy to try to find it.
Check a professional tax advisor as for each country there are different possible rules and depending on the kind of income it can change again. A professional tax advisor will only give you an advice for a specific and very detailed situation. But if afterwards you change your situation slightly it can change your fiscal situation completely.
Best is also to ask a ruling from the country where you want to go, if not you are NEVER sure that what the tax advisor told you, will be accepted. Tax advisors give only advice, the finance ministry will decide what you will pay.
The most simple thing you can do is move to Monaco. Deposit between 500k and 1000K on a Monegask bank account, maybe they ask even more and rent a flat. Starting price for a flat is around 5k a month for a very small flat. You need to pay 4 months rent in advance (3 as guarantee) and hope they will rent to you which is never sure.
The cheapest solution in Europe is to go to Bulgaria. 10% flat fee, and very small contribution to social security. You should live there at least 183 days a year.
