Did you ever had a transaction approved without fee or below the mempool recommendation? Look at this interesting conversation between @BitcoinIsaiah and @escodelrio
According to this article transaction fees are not mandatory: https://en.bitcoin.it/wiki/Miner_fees#Priority_transactions Perhaps miners will start confirming smaller UTXOs gratis in the future like they did in the past.
Yeah they aren’t mandatory, but who is going to confirm transactions with low fees? It’s all about profit.
They did it in the past. They may do so again in the future. Perhaps as a type of "freemium" model prevalent in other parts of the software industry. Many poor people may never be able to have more than a few thousand sats. IMHO Bitcoin has partially failed if they are left out.
Transactions with no fees will not get confirmed with a full mempool. Just not gonna happen. And yes, poor people will absolutely not be able to use Bitcoin unless changes are made.
I’ve had transactions with below purge rates come back and get processed. There is no single mempool so there are mempool runners that have a zero or near zero purge rate and will continue to rebroadcast low rates until they are processed or invalidated by double spend. Some mining pools will grab these low rate txns just to fill space, and clean the network.
This is why if you have a lightning channel open that has a low rate and it gets purged by some mempool filtering logic or lasts 2 weeks+, you have to double spend it or risk getting stuck in a multisig wallet with your node peer. They can and will surface and get processed.

I remember back when I started trying out Bitcoin that zero-fee txs were relayed and I made some myself. For a long time also 1 sat/vb was way more negligible than it is now.

A TX with zero fee will not be relayed by mempools. However, a TX with no fee can be added to a block.
Usually, zerofee txns are put there by the miner who mined the block. Maybe it's their own tx, or they got paid out of band to include it.
A TX with fee below a mempool's "purging feerate" will be dropped after about 2 weeks.
As long as blocks are full, its unlikely mempools/miners will permit any zerofee txns without some kind of reward.
What if the only change to BTC is that the fees come back down for a few days/weeks? Seems like then, the "poor people" could consolidate their UTXOs or open a LN channel.
