You're not really right at all. The percentage of fees that are passed on is completely dependent on elasticity.

is not even close to correct.

All businesses will increase prices to maintain the profits they need, up until what the market will bear - which is why taxes will also not end up pushing it too far, the gov isn’t stupid.
This is disproved very easily by reality - most places have increasing rent YoY. Same goes for house prices.
Because of low supply and large demand, like you say, landlords can charge monopoly prices. Not sure why you claim they don’t go up?
All this proves is that evolving market conditions lead to changes in price. Try charging 2030's market-rate rent in 2021, and see how many offers you get.
