For starters, if you understand that value is subjective, you'll also understand that there's no way to put a number on how much you want something, or precisely how much you'd be willing to pay for it, etc.
You'll also understand that you can't base calculations on something you can't actually quantify, and have no way of accurately measuring..
So yeah, you'll understand that most of what you've been taught is just garbage-in-garbage-out.
As for monetary policy, it's essentially just "a plan for forcefully intervening in an economy", and it doesn't actually happen for the greater good - it's done to benefit the government and their buddies.
As a prime example, who gets access to newly printed thin-air-money at zero interest? Do you want him to buy real assets with "free money", and have you suffer the consequences (of the resulting decrease in your currency's purchasing power)?
Counter-example: I do it all the time. Ever heard of "revealed preference"? Sure there are weird human things like preferring A to B, B to C, and C to A, but I'm OK with a map not being the territory.
> a plan for forcefully intervening in an economy
All government choices are forceful interventions, whether a choice to act or not act.
> Counter-example: I do it all the time.
No you don't. I mean, sure you can pull numbers out of your ass and pretend to calculate something based on them.
Or you can even explicitly set out to calculate garbage results with garbage inputs, if you insist.
But you're not putting accurate numbers on how much anyone wants anything, because it's all subjective.
> All government choices are forceful interventions, whether a choice to act or not act.
Indeed. That's how ruling over subjects works. I can't parse the latter part though, but whatever.
If that's pulling something out of my ass, well, I guess you're not a fan of statistics or the scientific method? Oh, actually, I forgot that's a central tenet of the Austrian School -- science is bogus when contradicted by philosophy.
> can't parse the latter part
If a government creates money, then it must have a monetary policy. Do you think government-backed money is not "for the greater good"?
Do you think 2% is a good rate for you to be losing your savings' purchasing power? How fast would you like gangrene to spread through your body?
Don't worry, I've spent plenty of time educating myself. Grad school was pretty good for that. It even says Economics on my diploma, heyyy.
I'm not sure what you mean by "monetary policy shouldn't even be a thing." That's like saying, "guns shouldn't even be a thing."
