... Furthermore the total fees per block are independent of the block weight. The net result of this is that if the block reward goes to zero the total fees paid per block also goes to zero. One conclusion is that in a Bitcoin like coin with a falling block reward in order for the Satoshi fee market to even have a chance of working the penalty in terms of the block reward for increasing the block size (weight) must be stiffer than that in Monero. One can then see the rationale for Bitcoin core's strict block weight limit. ...

By the way I prefer to see Bytecoin as the canary in the coal mine for falling block rewards as opposed to the scam in the pre or ninja mine.

As I mentioned above. If there is competition between miners then as the block reward goes to zero so do the total fees per block since the "penalty" in terms of block reward is less than that in Monero. At this point there is no incentive for the POW and the coin becomes insecure. The alternative is a mining cartel or monopoly that sets minimum fees. Quite apart from the centralization involved I have serious doubts  such a cartel will be sustainable in the long term since individual members will cheat.
