A couple of things here

One is that you and other miners are also "devaluing" Bitcoin every 10 minutes.

If you are actually serious about the prospect you would demand a hardfork to eliminate any supply increase.

Second is that "21 million only"is just a meme, it's not good monetary policy.

A simple look at the history of gold value shows that a hard cap is not necessary for good money.

They're extremely good reasons to NOT have a permanently deflationary economy.

Not to mention that Bitcoin foists paying for network security off on people who actually transact with it, Incentivizing hodling (hoarding). A Game Theory consequence which is already obvious today.

And Monero Supply is not infinite. It's guaranteed by mathematics just like Bitcoin is. You don't know how it's works and that's fine, But maybe just dial it back.
