The money doesn't come off the printing press out of thin air, it's a redistribution of wealth. That is, additional wealth (or currency which is an abstraction of wealth) isn't created, it is redistributed.

That wealth can be used to consume the same amount of goods/services that it could have before the redistribution, but now many users get to make those consumption choices instead of one or few.

Yes, this redistribution will have a massive impact on the _pricing_ of different goods and services within an overall market. However, total wealth (ability to consume in aggregate) will remain the same within that market.
