UBI has been tried experimentally around the world many places including the US and did not have that effect "the money people had received was not squandered on frivolous products such as drugs and luxury goods": https://en.wikipedia.org/wiki/Universal_basic_income_pilots

Which experiments were successful depends on what your desired outcomes were, but none were as bad a you suggest, I would say many succeeded.

I do not know how COVID support worked in the US, but one of the things you refer to seems to be loans to businesses, which is very different from UBI. Were people given a fixed and guaranteed income stream not linked to earnings during COVID?
