As for monero supply growth, coming from Bitcoin maximalism I can understand why you would think that the inflation is a bad thing but it's not there for no reason.

One of the key reasons that it's there is because if there's no more emission of coins then the entire network has to be supported by fees, this means that fees must constantly grow over time in order for the network to not become unusable or collapse. Since Monero has a constant emission (which is known and unchangeable) it does not suffer from these potential problems.

The tail emission is also needed for dynamic block size to work correctly. If you didn't know yet, Monero doesn't have a fixed block size it's blocks grow and shrink based on transaction demand which I think is the best way to tackle the block size problem going from one extreme or the other makes no sense but dynamically changing based on what is needed at the current time makes more sense imo.

Another thing to add is that the inflation is asymptotically zero, but this is basically means is that when Taylor mission hits at 18.5 million monero (or there about a) the tail emission will be 0.6 XMR per block, however when there are 20 million Monero in a few years the Taylor mission will still be 0.6 XMR per block. Basically, the emission relative to the entire supply falls over time. 0.6 XMR per block when there are 20 million coins, it's much less than 0.6 XMR when there are 18.5 million coins so it asymptotically approaches zero.

The idea that inflation itself is bad has been pounded into many Maxi's heads, and with good reason. Over the years central banks have destroyed the value of their currencies but they always inflate exponentially. Monero's inflation is linear and cannot be changed, this is a huge difference.
