Re: Ordinals and other non-monetary "use cases" as miner reward on 2140+
As for the fees, they are 4% of the reward, if you expect people to pay 30 million for 400k tx day, well, how can I say it... don't! 
Let's not forget that higher fees (in BTC terms) are a result of higher transaction count, if Bitcoin will be used only for big transactions as some say then of course transaction count will be smaller than what we have today.
You can't expect to have more big transactions than small transactions we have today.
