Exactly, the separation between server and client and the huge complexity and annoyance in hosting is exactly where the imbalance is that deeply centralized everything around the web.
It literally all stems from the difficulty in hosting through network configuration, the complex stack of website creation, the difficulty and tedium in ongoing management, the lack of persistent identity (thus social connections are owned by the site, not you), and the high cost of bandwidth on public servers…
All of this leads to:
huge centralized hosts, smaller hosts that simply resell huge hosts, centralized app platforms with ridiculous margins for owners purely due to network control, and centralized+censored social media that’s horribly difficult to compete against.
If you can solve Identity and connection without a third party AND kill the separation between client and server… you have fundamentally changed ALL of the above dynamics that tend heavily toward centralization.
