I know I understand what I said, and I am not convinced by anything you said. What reliability problem would prevent you from running local-first software but doesn't interfere with running a thin client? Why would the business logic part of your app require more RAM on the end-user device that it requires per-user (or per-document, etc) on a server? Why do you claim that running migrations is so fundamentally different here and there? If you want to argue I would appreciate you doing it with real arguments and experiences rather than even more unsubstantiated claims and statements like "you don't understand what you just said".
