@rocks lots of interesting points in your post. I do wish however this thread becomes less about BSV vs ABC vs BTC and more about the tech and/or opportunities afforded by those. Lets also move off the personality driven discussion CSW vs Amaury vs Greg (which I think you are aligned with).
So on that note:
BSV however allows storage and computation to happen independently of full nodes and creates a better balance
So if BSV is removing OP_RETURN limits then it will still require full nodes to download the complete OP_RETURN data, even if they end up pruning that data. So a lot of network traffic and temporary storage just for data that most nodes will prune. I suppose though that the benefit is strong economic backing of that data compared with systems that just hash into op_return and store file data elsewhere, which only provides economic backing of the hash, not the data itself.
Computation: You mentioned computation off chain, but not sure what you mean. Yes I can store a program in some large op_return and let others run that program. Sure. I can also store smart contracts in op_return. What I can't do without changing the protocol more, is ensure that smart contract execution is backed by BSV proof of work and BSV node validation. Even ideas like Bitcoin Token project by Clemens Ley (and arguably patented by nChain) AFIK require other nodes running another protocol to validate execution, similar to Omni or other protocols. But I never could parse all of Clemens's claims about it.
Both of these items (storage and computation), are more of the direction that Ethereum went. Frankly Eth is IMO under appreciated by BTC/BCH/BSV folks because of tribal bias. It has smart contracts, node based execution of smart contract code and storage of its data outputs, and people are building Swarm for a fully decentralized file storage system linked to Eth chain. They have dapps, and even if you disparage the ones currently in place perhaps you can appreciate the concept.
So BSV heading more into the computation/storage realm is interesting, but doing that without changing the protocol will give them limitations that they might not be able to surmount. It also completely shifts the idea of Bitcoin as global money to something else. More than likely though I see BSV being used as base storage and money layer and other code/chains being used to do further work.
