Why is it impossible? We do that all the time in countries that are not USA. Sometimes it is even successful. This all depends on how budget is allocated. The main drawback is currently that people do not vote directly on budget allocation and representatives have vested interests more often than not. (Except perhaps in Switzerland.) We could change it, but transitioning such a system would be hard and there's always excuses of "strategy" involved. As to art itself.. Governments also sponsor some forms of art. (Sometimes this gets corrupted or politicised.) Heck, there are private foundations too which do not have a single or small number of rich patrons.
