As you may have noticed, most coins have a block reward eventually reaching zero with expectations to run off transaction fees, while other coins have a perpetual, non-zero block reward. Not much attention has been given to the relationship between these two parties. While Bitcoin can be used as a store of wealth, the Bitcoin protocol's primary usage is a transaction medium. The zero sum market dynamics will face each coin type against each other, the ones with zero block rewards, and the ones with perpetual, non-zero block rewards. For a person using the Bitcoin protocol as a transaction medium, as I mentioned was it's primary usage, and not a store of wealth, that person should always find lower transaction fees in a coin with perpetual, non-zero block rewards.
The point I am getting to is, one party has already won this war before it started. The zero block reward, transaction fee only coins will either have to adapt or be destroyed. This doesn't mean that cryptocurrency has to become Keynesian, or highly inflationary in nature. Through accidental loss due to strong encryption, human error, misplacement, death, a large number of coins will be lost per year in any cryptocurrency. Estimates can be made as to what the average percent of coin count per year that number is. This number can then be leveraged as a non-zero block reward. The goal of a transaction medium after all, is not to be deflationary in the first place, it's to remain constant in nature.
Satoshi didn't like the use of "magic numbers" in the Bitcoin protocol, but I think a clear range of values will be discovered for optimal non-zero block reward. My personal estimate is between 1-2%. People such as Anonymint have argued 2%. Using the upper limits of 2% would most likely introduce a small form of decentralized inflation, so that is a factor to take into account.
