I don't think the deflationary nature of btc and other crypto that are a finite in design is necessarily a bad thing.

The most common objection is that it leads to intertemporal decisions. Is that really bad?

If you knew that your money increases in value over time you might only spend it when it's really necessary instead of driving an ever expanding economy that consumes a finite world.

Maybe a finite world needs a finite economy?

If my money reflect the wear and tear on our common ecology I might be more restricted in its use.
