Communism is when the government owns all property and all factors of production. UBI does not involve the government taking over anything.
Very likely ends badly, as voters seek to increase UBI to infinity.
Considering how much doubt there is among UBI in the first place, I don't know why you would assume politicians and voters would just want to endlessly increase the size of monthly payments.
Sure it does. In this case the money for UBI has to come from somewhere. It will come in the form of extremely high taxes. If the government gets to keep more than 50% of your income, then they are a majority shareholder in your individual output. They retain extraordinary power and control over you. And that could ratchet up all the way to 100% theoretically under the UBI system. There really is nothing stopping it from happening other than voter sentiment.
There might not be favorable sentiment now, but sentiment can change. But I do suspect that if you implement such a system, society will become dependent on that system. And it will be ratcheted up to pander to populace. It would be a powerful tool for politicians to garner favor. I've seen it done in other countries that openly embraced socialism and populism. It ends in economic catastrophe for nearly everyone.
