Better healthcare? Wonderful. More like-minded people who share your values and interests? Sounds great!
But a valuation means literally nothing. You could just as well have a country full of "unicorns" that absolutely do not improve society and result in crippling socioeconomic inequality.
I also don't understand the point about the bureaucratic German system. I've lived in Germany, and yes, the bureaucracy can at times be annoying. But are you really going to base where you live your life on how difficult it is to incorporate a company, an activity you will do at most a few times?
I also hope that you are now in a country that will help you "become a founder more quickly and increase the odds of [your] startup being successful", but I trust you already know that these odds will be overwhelmingly decided by your own ideas and work, not by the specific legal details of limited liability companies in your jurisdiction.
I truly hope OP finds a lot of happiness and a wonderful life in Estonia, but if they do, I don't think it will have been for the reasons they expected.
(Note: nothing against Estonia, I've always wanted to visit)
