Yes it can be supported by a future firmware upgrade (which is in fact planned for a while now).

The clients I've used all support taproot but the device can't handle it yet.

Bought two of them a while ago but I soon found out they do not support taproot addresses which makes them useless for my intended use. Cool devices though.

Ah yes for sure. Totally forgot that live-action movie even existed.

Ghost in the Shell

Be careful though, if you have a mixed fee structure (serving both cheap rebalance txs and high priority/time_pref txs) then it's hard for your peers to price you and your volume might suffer.

I understand the "21 million forever" concept but that's not my question or the original question (I think)

What do you specifically think about the idea of a fixed reward that Peter Todd recently opted for discussion on the bitcoin-dev mailing list?

In short: organically coins/sats are lost and therefore a small inflationary reward for miners might not absolutely impact the 21 million cap.

Point well made and taken. Too early to think about it.

I was hoping for a more nuanced response from @softsimon since he is more aware of the fee market development and likely has thought more about it therefore.

How do you know most bitcoiners disagree? Is it subjective or do you have some data?

I've been following the fee market development closely and I am not that optimistic. Once I thought that introducing an inflationary component to bitcoin was heresy but the past few years made me question that.

What Peter Todd suggests does seem to make sense considering the coins that are lost in organic ways.

Bitcoin is becoming increasingly important to the energy sector and having a tiny block rewards without any meaningful fees will impacts that progress.
