We were lucky to have enough remote work (online teaching - one of the good outcomes of the pandemic for us) to keep our work when we moved. For live concerts, of course, we had to restart our community and connections, but after so many cancelled concerts for the lockdowns we realized how unreliable those were anyway.

If my kids were still small, this would have been a more exciting move (time outside, real connection to soil and animals...) but also much more difficult in terms of urgency of building local community and connections. 

Once you have community, you can work with others to help each other with livestock chores (and there are a few things you can build in - automatic waterers, automated chicken coop doors). However - yes, in general you have much less flexibility. 

A lot of families manage homesteading with jobs, and even with jobs and kids. You just have to choose your projects carefully.
