I do not think on chain fees under 10 sats will happen very much anymore.
There is simply no demand to keep them afloat once all the consolidation for 6 months of pain and the ordinals are gone!
Look right now at the blocks, it's 1/3 consolidations and 1/3 ordinals, actual demand for transactions outside those two is minimal, and consolidations can't keep it up since you need first the tx splitting the inputs first!
as there are unstoppable methods large farms can do to make their profits higher.
you can not stop a 30% pool from down clocking and slowing blocks to clog the mempool then once the mempool is clogged bump hash up to grab high fee blocks...
And you can't force people to make transactions either!
It's pretty simple, they can reduce the chain capacity to 10blocks a day, if there is no demand for space as ordinals hype dies and most action happens anyhow on CEX and even off blockchain completely like ETFs there is nobody who will pay you three times the fees. Of course here I ignore the misconfigured bots that pay even now 450sat/vb.
Think of it as a toll tax, once you make it worth 10 gallons of gas people will just drive around it!
We just saw 8 sat vB about 2 weeks ago.
We're in a middle of a bullrun and we're still at 12sat/vb, I don't see where any extra traffic going to come from, I think feebudy is going to need counselling soon.
