Have you read the Bitcoin whitepaper? You should, it’s not that long. This is not what was promised. We were promised a decentralized peer to peer currency with a fixed supply that couldn’t be inflated at the whims of a central bank. We got that. And we sort of also got “new forms of interconnected computing”. We now have new types of zero knowledge proofs which were designed for smart contract verification but are more generally useful. We have things like IPFS allowing you to store data in a decentralized way. There’s helium, a mesh network for IoT devices. We have ENS. Then of course we have an endless supply of sophisticated financial instruments which you probably wouldn’t be able to access otherwise.
Your position is easy to take because it’s sort of the “default” that an uninformed person would believe, and those people will side with you.
