The #bitcoin block reward's ultimate purpose is not for revenue. It is to bring new bitcoin till fixed supply is reached after which it stops.

transaction #fees are the real income, meant for the #miners. Satoshi had set a block size limit of 1 mb, because he didn't saw rising fees as a problem. He saw it probably as a the traject in which the miner income transitions from:

-

the unfit, unadjustable, short term means to distribute the limited supply of bitcoin, AKA blockreward,

-->

adjustable, appropriatly tuned, user input based, feemarket.

this traject is over when the last bitcoins are mined, it just happens. but smaller blocksize, is really important. We should and have to reduce the blocksize back to 1 mb.

-

also important to note, higher fees is inconvenient, but it is a necessity. You can't expect the immense security of bitcoin to be for free. You have to pay for it.
