I think I see where you're going with this, in that money is not an issue, but rather tangible goods.

However, it sounds like you're assuming that we should keep our same level of productivity or else bad things will happen.

I think we can lower our productivity and be just fine.

The sheer volume of choices that we have today when purchasing anything: costs, sink faucets, roofs, cars, wallets, shirts, is unfathomable 3 generations ago.

There will be some fall off of choices, for sure, but that's not necessarily a bad thing. We will just have fewer people making less stuff with fewer options. If what you say is true, and the US can meet its financial obligations through money printing, then we'll just have a "lower" standard of living that is still pretty damn high.
