The problem will increase with adoption. More people are coming in with less deep understanding of Bitcoin. It’s definitely a danger.
Discussion
I remember you complaining about high tx fees driven by spam not too long ago and now you're saying Bitcoiners who are concerned about Core intending to remove the OP_RETURN limit and allowing even more spam are a threat to Bitcoin?
(I'm missing any earlier context between you two)
As a relative noob myself to this discussion (I spent a few years in my hodl-cave ignoring bitcoin), I don't think it automatically follows that "spam is making tx fees too high" means that's it's either necessary or sufficient to do more filtering in the mempool
There are many issues and incentives to consider
I still feel that non-monetary data shouldn’t be on Bitcoin. But the problem isn’t solved by running knots.
Yes and no. Adding more nodes is - I think - never a bad thing, even if those nodes do stupid things
As long as there's a reasonable number of sensible nodes, they can find each other and keep the network going
(Or maybe I'm oversimplifying and there is a risk?)
What would need to happen for it to become a BIG problem?
