I don't believe that honestly. There's many facets of what Bret is making here. Not all of them require a physical presence, the COVID lockdown and years of internet communities before that have shown you can build vibrant communities online.
Many of the ideas can be worked on and improved without requiring the expensive physical space so the OS and the concepts of the composed tools they talk about for the future of the project can all be improved and played with in a virtual space too separate from the physical presence.
I did not intend to discourage the idea! I think it sounds very cool and potentially worthy of study. But I really do think you're underestimating the difference.
