Money is just a mechanism for resource allocation - there are many unemployed people, and there is much infrastructure that needs fixing (not just physical infrastructure, but also social infrastructure).

The Fed has changed policy, 2% is not a maximum anymore. With as much government debt as we have now, inflating it away is the only realistic way to get rid of it.
Higher inflation reduces debt over time. You take on a mortgage and 10yr later paying it is cake because the debt doesn't track inflation whereas your pay does.
Lot of countries around the world intentionally debase their currency to stay competitive. It's a valid monetary instrument. In the short term, currency debasement would lower the standard of living of Americans, but it would make their labor competitive.
