Inflation is too uniform, I guess. Why not just take the $100 bill out of circulation?

Also, this seems to be falling into the classic fallacy that sovereign governments which control fiat currencies still levy taxes for revenue. Yes, it keeps things conventional and understandable to think that way, and yes, some forced circulation of currency via taxation is necessary to keep it alive, but broadly speaking, an entity like the U.S. Government does not need to collect tax revenue to function. The purpose of taxation at that level is to shape behavior and so effect policy outcomes via nudging. That still might justify a "high-denomination" bill tax, but let's not kid ourselves about "making up for lost revenue".

Do you mean that the government could merely print money instead of collecting taxes?

That would trigger higher inflation, which would have some very nasty consequences. Assuming you're thinking of the EU or US, it would effectively kill the Dollar / Euro's status as a global currency.

Really?

> The primary sources of revenue for the U.S. government are individual and corporate taxes

Wouldn't it do almost nothing if it did not collect tax revenue such as income tax and land tax?
