I don't think infighting is damaging... Its healthy. Everyone can choose to speak with maturity or immaturity, then sort themselves accordingly. I also don't think forks are damaging. Roll backs are damaging, though.
And although I've been against core30, I'm actually not even against arbitrary data. 3d printer files are an example of something I want to be there. And who knows what will be good to have in the future... Plasma guns or plans to the death star.
The problem is threefold : malicious data or executables ; junk data ; and the mispricing of putting it there. The first two are hard to define, and would be partially fixed if the third was fixed - meaning, more expensive. A lot more expensive. It should be stupidly expensive. Anyone considering it should feel indignant at the cost. That's the filter that would work, while keeping the potential value of arbitrary data.
So then the real question is, how to make data storage expensive while keeping transactions cheap? Whatever the answer to that is, is the answer to fixing bitcoin. Yes, it needs fixing. It is broken. The witness discount broke it. Base layer transactions never needed to be cheaper.
Maybe people are saying this stuff and I just don't know how to listen in. But so far, I haven't seen **_anyone_** thinking through this clearly. Every discussion - **_every one!_** gets stopped by idiots chiming in with inanities that were useful in the past but are just too low resolution for this discussion ("bitcoin is money! Bitcoin is for enemies!" Or any other short phrase they learn from podcasters). The discussions stop right there, maybe because people get bored and leave, idk.
