*Unpopular opinion alert*

Bitcoin will have tail emission in the future. There's no other way, with the current system a point will come in which block reward will be irrelevant compared to fees. At that point, miners will be either:

1) State financed, thus they will not bother with profits anyways, or

2) will be gasping for money. There will be q serious incentive for block stealing instead of focusing on building the next block.
