I don't think that Ordinals are problem. Ordinals are basically shit but people are willing to pay lots of money in this shit. If someone wants to buy a shit for thousands of dollars, who am I to judge? Let them buy it. I think that number of Ordinals users will decline because those NFTs actually carry no value, absolutely no value and over time people will analyze that shit shouldn't be valued over good. But blockchain size is still a problem because as number of bitcoin users rise, number of transactions will rise too and it should be cost-effective for people to use frequently.
Do you realize you are exactly mimicking a no-coiner point of view in your post? Many no-coiners invest in bitcoin or any other crypto thinking the exact same thing. “If these morons are willing to pay their hard earned cash for these useless pixels, why shouldn’t I profit from their stupidity?”
If you truly think NFT’s are dogshit, then you should also support the removal of NFT’s from btc. Just because somebody is making money from selling dogshit, doesn’t mean that we all have to like eating dogshit.
