> addressed through mechanisms like the provision of healthcare, UBI, equality, or addressing inequality then perhaps society can be structured to have a very minimal government
The (most likely/obvious implementation of the) first half of that seems diametrically opposite of “very minimal government”.
Having a government that's there to do no more than take in tax receipts and spend the money on essentials would be minimal compared to what we have at the moment. Right now the government involves itself in practically every aspect of people's lives. It doesn't have to be that way.
But your minimal government wouldn't work. If you have taxes then you need a justice system to enforce collection of taxes. You'll also need a military to prevent outsiders from taking your treasury.
