Printing money only makes money worth less, not other goods.
Because of that, it would ‘tax’ those with more cash and fewer goods more than those with less cash and more goods. for example, that would mean it would ‘tax’ house owners less than renters.
One could argue that is fine, but in practice, poorer people cannot choose between renting and buying a house, and some would find it unfair to have those poorer people bear the burden of paying for the operation of the government.
It would also lead to inflation. That would make currencies of countries that print less or no money more attractive. So, the situation where all counties print money instead of raising taxes might be an equilibrium, but it won’t be a stable one. A country that switches to raising taxes would see its imports get cheaper and cheaper. That’s good for it’s citizens (to a limit, as it also would make exports more expensive)
