You bring up an excellent point. Let's take it to an extreme and then attempt to disprove it. Consider a future of hyperbitcoinization where Bitcoin price in dollars as we know them today is astronomical. Only large corporations or the elite could afford an on-chain transaction. You would not be able to open a lightning channel due to lack of mempool space and funds. Channels would all be owned by banking types (which are the grandchildren of hodlers today). Governments begin to legislate regulations regarding mempool priority. Governments may force miners to mine a certain percentage of underfunded txs in an effort to quell the satless. And the Governments could enforce it because they will be backed by the masses without Bitcoin demanding relief from mining farms and channel owners. Because no one fought for privacy improvements in the 2020s, employers pay wages in Bitcoin but to do so you must register your zpub with them so they can pay a new address each time and track their payouts for taxes. I suspect there is a point of expense where users would create fiat IOUs again or resort to trading keys instead of transactions. Maybe your small denomination addresses would be the best result because you wouldn't need as much change?
