This is where you and I disagree. I say we should not allow bitcoin blockchain to be largely used for something other than a "peer to peer electronic cash" ledger, in this case for cloud storage.
Neither do I want that, but I want it less than I want to not turn Bitcoin into a censorship nightmare. I'm honestly curious if you've read my points. There's no way to prevent someone from using it as a cloud storage; yes, you can disincentivize financially, but we already do that. It's called block size limit. Anything beyond that introduces subjectivity into play. If there's real demand for these Ordinals, which I think it's questionable but say if, then it won't take long until they avoid your "measures" and turn into indistinguishable Bitcoin transactions.
