Continue where you left off, except without access to OpenSea (or whatever other vendor), in an economy where the value of the contents of your wallet is increasingly dependent on the availability and visibility of your "digital assets" on vendor services.

But you're right. Decentralization is not the problem that the crypto community is trying to solve, because they don't actually care about a decentralized "Web3". They care about the parts of the system that make them rich. The "decentralization" cant is just social-good camouflage, no different from Facebook's claims about making lives better through the "metaverse".
