Seigniorage is fundamentally dishonest.
Money, either minted, printed or digitally created, is used to provide the economy with a means of payment and to generate revenues for the governments to finance public spending. Each government uses seigniorage to provide public goods. ...
I don't disagree with what you've posted there. Yes, governments use seigniorage in order to fill the government's coffers with money they use for public good. And, incidentally, for public bad.
But you are sidestepping the real issue.
Seigniorage works by taking (I would like to say 'stealing', but I'll be more polite) a portion of wealth from all of the people. The creation of new money is a very real taking of wealth.
Governments use seigniorage rather than taxation precisely because the overwhelming majority does not understand the mechanics of money. This is an invisible tax. By capitalizing upon the ignorance of the masses, seigniorage is fundamentally dishonest.
