Greece is not a example of the people voting for more UBI instead of working, nor was the effect discussed related to what the government can afford, it was related to fundamental economic limits on the ability to raise real levels of a UBI no matter what happens with nominal levels.

That people can vote for a government which enacts policies which have an unsustainable balance of spending vs revenue is true independently of the presence of absence of a UBI, and not any kind of argument against a UBI. And it also has inherent limited, as seen recently in Greece, by access of the government to credit.
