I know of one country where you have to be in-country for more than 183 days to be taxed. If I spent that much time at home, it would be worth the tax. But besides that, it is, like with just about everything else a very subjective matter. What may not work for you, may be just the thing I need due to family problems, health issues or even extended family problems. No-one can judge anyone elses affairs unless they are in exactly the same situation, which is unlikely.
