Wow, that's nice. EU also is nice in that some countries have next to no taxes and yet with their passport you can travel anywhere else in the EU. Best is if you can set up a firm for billing purposes so you will pay only that country's minimal corporate tax and minimal income tax, in some cases if you can manage a year or two you can mostly move to just paying yourself dividends or equity which is even cheaper. Even in Finland if I had enough money accumulate to privately owned company I could theoretically pay zero dividend tax on the capital income and, say, pay myself a year's income in January or so with the option of always being allowed to pay any bonuses etc. that would be needed. And if I'm either still single or so at that point there's really no point in keeping an expensive boat in a warehouse from autumn to spring when it could be in Riviera...
