I may be hated for saying this, but what's currently happening in the mempool is a feature, not a bug. The fact that we have a fixed-sized block limit means that the current clogged up state would inevitably happen sometime.
I'm going to disagree with you. The fact that Bitcoin is currently useless for small transactions, and very expensive for large transactions is a serious problem.
I never said it isn't a serious problem. What I said is "it's a feature". Here's another feature: 21 million cap. "But this might not sustain the miners' income". I know. It might not. But, it's a feature nonetheless. Same applies to a fixed-sized block limit. It's inevitable that rich people will outweigh the poor sometimes, in terms of confirmation priority.
I think that in times like these, where we have multiple sides siding against different opinions, it is important to remember the very first words that stood the foundation of what Bitcoin is today:
A purely peer-to-peer version of electronic cash would allow online payments to be sent directly from one party to another without going through a financial institution. (...)
By simply existing the feature to implement such protocols doesn't actually mean that they should be created/implemented in the first place. Sure, adaptability and flexibility are great in the technological era but I believe that there has to be a core idea that would have to be followed in making sure that each ramification of the technology stood the ground against their foundations. Otherwise, what would it stand for?
I'm not against progress and improvements to the concept of Bitcoin, don't take me wrong, but I can't seem to find a reason to believe that adding NFT imprints in the blockchain is something that would allow the technology to remain faithfully to something it stood to reach (someday).
I'm now teaching my kids to use Monero
You're a father figure! I wish I had a father who taught me about Bitcoin and Monero. Congratulations.

That is an astonishing feat, congratulations to you in introducing them to both concepts. I wonder if they realize the main differences between those and fiat and what were their first opinions about them?
I just hate seeing Bitcoin lose market share to shitcoins, because Bitcoin can't handle the transaction volume that comes with it's popularity.
The sooner we accept that Bitcoin cannot handle the entire populace on-chain, the better. Free markets are trial-and-error based. If Bitcoin has erred as electronic cash, then it's down to us to see which change in a crypto-protocol would make it look more like cash. Maybe there is none. Maybe it's dynamical block size. Maybe it's tail emission. Or even a compression method we haven't even thought of. In practice, we can see which is more recognized as cash.
This is an acceptable discussion and one that has been going on for some time and I easily see more this as acceptable regarding what can be made than Ordinals/Rune implementation and is totally understandable that Bitcoin simply cannot answer with efficiency when nothing could prepare us for these new NFT concepts when Bitcoin was first created. I wonder what more can/will be created that we haven't imagined regarding Bitcoin - ~ 14 years to create "fungible NFT" on the blockchain, I wonder what it may come next. As an additional perspective, not one of my friends in real life, those who just want to hold bitcoin, is aware of what is going on regarding high fees, fungible tokens, Ordinals, Runes.
But then again, like BHC said, the free market is the concept that dictates this behaviour - if people didn't care about NFT, these implementations wouldn't have any kind of relevance. Problem is, I don't see NFT going away any time soon and with the amount of bridges being made for the Rune implementation, I fear that this may just be the beginning of a troubled period in Bitcoin existence. At least for a while.
