If you'll try to replace taxes with printing money (which is effectively a tax on owning money), you'll just destroy your economy, because no one would want to own money and the inflation would be much higher than what would you expect from simple calculations. Taxes can be very complex, there are tons of rules that can increase, decrease or even remove taxes for certain situation, meanwhile printing money just affects everyone the same, so this idea is much worse than taxes.
I agree. A better idea would be to remove the direct taxes (income tax, corporate tax.etc) and replace them with higher indirect taxes (Value Added Tax, Goods and Service Tax.etc). This will make sure that the richest category can't use loopholes to avoid paying taxes. Also, the tax base will cover the entire population, rather than those who earn above a certain threshold.
