To me this is rhetoric that conveniently ignores the sole advantages of blockchain and distributed computing.
Blockchains don't exist to be fast, efficient, or scalable. They exist to be decentralized, permissionless, and censorship resistant.
> People are trying to move from a world in which compute resources are efficient and almost limitless to a world of scarcity because they want to build an economic system where you can trade your fortnite skins for online currency
Actually, no one's doing this. You've created a strawman argument. Netflix and Youtube aren't moving their hosting to the blockchain. Google's not storing database shards on IPFS. What people are trying to use blockchains for is the creation and persistence of digital property. Blockchains are expressly better at provenance because records cannot easily be altered, compared to a centralized service.
> Creating economic ownership schemes of things that nobody needs to own because they're not scarce in the first place.
Congratulations, you just defined western capitalism.
