I want to say that I'm not 100% sure that my perceived scenario will 100% be as written, as there might always emerge things that we do not see yet.
1) You also "run" a plug that sits in your wall, that allows for TCP traffic. That traffic does not care if you are watching porn or browsing wikipedia and also, it shouldn't. TCP CAN be used to stream porn, although it was never meant with that goal. Even with unlimited OP_RETURN, the consensus rules stay the same. And AFAIK (I'm not 100% sure): What your node filters does not matter at all, because miners will find a valid block and as long as this does not cause a hardfork, your node is going to accept the found block. Your filter basically is only for you and the users of your node. And for Matthew Kratter, so he can say "8% of nodes are Bitcoin-Knots nodes", which is a meaningless number, as of my current understanding.
2) Yes, monetary transactions will be more expensive IF THE BLOCKS ARE FULL, which is an important note. First thing is, that we want to have full blocks, for keeping the miners around long term and not put them into a stop and go mode. That would be the worst thing that could happen to BTC, because the 10 minute block time would become heavily volatile. Also, monetary transactions will move to a second layers solution, which is already the case now for small payments. Your spam concern is imho correct, I also am a bit afraid of that. Even if economical incentives speak against it, there is actor A which has 9999999x more financial power than actor B which also wants to use the mainlayer once a year. That being said: Spam is already possible and it doesn't seem to happen often. Having a bigger OP_RETURN does not automatically enable spam, it just opens the path to developers for easier NFT access, but it's not like the could not do that stuff already with multiple combined transactions. The block size limit remains, so your node doesn't suddenly have to get bigger SSDs and so, as you should anyways calculate with full blocks when you want to decide on how long long the capacity of your SSD will need to last.
>it's already so hard to make ppl understand what btc is
Nobody understands what bitcoin is. Not you and not me, but we have a vastly deeper understanding of it than the majority of people. But you see on this debate, that even the biggest experts on bitcoin have different approaches. Bitcoin is what democracy decides it to be, nothing more and nothing less. If you believe that YOU got it 100%, then clearly you should work on yourself, before you start on others. I can't count the times where I had an opinion but I wasn't aware of a simple additional fact that made me completely shift my opinion. Some of that stuff is already known but you don't know it yet, some of that stuff will emerge only in the future.
Thanks for writing back man, I appreciate such discussions and I don't claim to be right, I'm just not convinced otherwise yet. :)
