literally no economist EVER suggested having a monetary system with a fixed number of units.
"you know what would be great, in fixing the price of money if we could just take the supply side of 'supply and demand' completely out of the equation. that would be great"
You're just making things up.

what is "good and natural" is for the macro environment to fluctuate between slightly inflationary and slightly deflationary in a deregulated and uncontrolled way depending on human productivity.

also what makes something "theft" or not is consent. you consent to Bitcoin supply inflation, therefore it's not theft. it isn't any different with Monero.
so stop with the meaningless kneejerk maxi dogma.
