I would add people who change jobs and households with more than one worker.
Nobody is going to move every time they change jobs.
Approximately nobody is going to live close enough to the workplace of everyone in the household who works.

Then who is going to be left to support the walkable economy? You need approximately every working person who lives within that community to be active in the walkable economy, else you will quickly find that services are no longer within walking distance.
Are you imagining that you’ll hop on the train to go work on the other side of town, while someone living on that side of town hops on the train to work in your neighbourhood? That is not a good reason for transit at all. That’s just silly.
There are many problems with the idea that every community should be so maximally walkable that you don’t need any other modes of transit. Some urban uses like parks require local low density in an urban setting and they can easily get large enough where 20min walking barely gets you across. Also the social network of people even just including the closest friends and family usually even in dense cities spreads out at least a few km. Also super tall buildings aren’t actually particularly efficient. Also some services greatly benefit from a certain centrality that can never be in walkable reach for all people of large cities e.g. universities or other more specialised institutions. Transit and bikes are huge enablers for people to freely live their life as they see fit, and some level of global interconnectedness is probably needed forever. Build one efficient medical supplier, steel mill, semiconductor FAB or generally any larger factory and walkability is immediately gone just because these facilities need lots of space, and their entire supply chain would be much less (thermally/CO2/resource) efficient if we were to split theses factories to enable local production.

Who do you think is going to maintain friendships across a few kilometres? Maybe the hardcore walkers, but the average person is just going to find new friends, just like they do now when distances become too great.

That’s a feature. Have you seen how much Canadians bitch and moan about wealth inequality? Splitting up central operations into small, local operations is how you beat wealth inequality.
But I get it. Change is scary.
