Here's my 2 sats.
Fast forward two halvings. Block rewards are 75% lower.
Fees or price has to climb materially from current levels for Bitcoin to be as secure as is today. If block space isn't scarce, fees won't climb. If we don't have enough fees, then Bitcoin can be hacked if the price is low.
There are two ways for total fee security to increase:
  1. Number of on-chain users remains fixed, but they pay higher fees per transaction.
or
  1. Number of on-chain users increases and they pay the same or less per transaction.
Both options create more security for the network, but one cripples the chain to actual real-world use.

As Luke DashJr has previously suggested, reduce the blocksize to 300k thereby increasing scarcity for blockspace which would consequently drive L1 fees higher, and reduce/extend low cost operation of bitcoin nodes.
