UBI can be changed gradually. It loses some of it's efficacy in distribution but it doesn't need to be revolution. It can be evolution. It also does not mean a high risk of capital flight for the first movers. This means countries or areas can do it incrementally, one at a time, rather than a complete global shift at once. The wealthy won't want to give up their wealth, that's a given. That is the case for any change we plan for better distribution, so it's not really an argument against or for any change.

Yes, it favours capital accumulation and rewards poor behavior. So what I have suggested adding is a method that leads to better wealth distribution and to disincentivise the negative externalities. Correct the flaws, so to speak. There is no perfect system that cannot be exploited. It's a case of risk mitigation not elimination.

Socialism may stop companies doing shady shit, but will it make them.less competitive on the world stage? Remember, they are competing with non socialist countries initially. As you mention, it would be a means of transition. Yet, every country that has tried communism has failed, often with devastating consequences for the people there. Our world and nation state economies are much more complex and intertwined than before, yet efficient use of resources was not possible then. The problem is not the theory, it is people. Power corrupts.

I don't have a problem with changing the ownership structure. However, can you point to any cooperative that was able to scale in the way that modern companies in a capitalist system do? Cooperatives exist and on a local scale can be beneficial. On a macro scale, they are less efficient and society as a whole is worse off for that loss of efficiency. That is the problem. Capitalism priorities profits, which require growth. The key is not to ensure broader ownership, but rather broader distribution of the wealth and profits created by that. We already have examples of that with share disbursement as a reward. Perhaps we could look at that being a regulated norm, in tandem with pensions payments etc.
