The government needs money. It prints a fixed budget for the year say 10% of money supply. Boom, 10% instant inflation spread evenly across all money holders, those who have more, those who have less. In one second, one enter key, all the money government needs right in their pockets, no need for infrastructure, monitoring, personnel, overhead, nothing. Clean money ready to use.
Land Value Tax as Henry George proposed, while philosophically sound, it still requires collection, measurement, vigilance, etc while Money Printing Tax MPT does not. We have a trillion dollars in circulating money, we print 100 billions. Next year we print 110, and so on (whatever the math is) and they both cover the same principle, money for the government to work extracted the most equitably from all at once
If the government ever needs more money say for real wars, threats, national disasters, it prints more (special circumstances approved by congress 75/25), everybody contributes proportionally to their wealth, and nobody would ever complain
You say in less than ten years the money supply would double and the currency debase? So what? In real life, the government printing money only benefit those who get the money first, while with this method everybody is affected equally so there is no advantage at all
Thing is, the insatiable appetite of the state for money no matter where it comes from is impossible to tame and no matter how many ethical thoughts we put on it, thieves in power won't ever care as that's their nature
