They actually often are in the short term (see the "significant loss of productivity from which it took the agencies years to recover" quote in the article about the similar relocation from Trump's first term), and a gutted department of agriculture can remain incompetent longer than you can avoid supply chain disruptions and food poisoning.
What you do is open small distributed offices led by a driven person eager to live in that area, and let the small offices grow over the years as the DC offices shrink. Careers aren't that long on the timescales governments work on, you just have to be patient and be ok with slow, incremental progress in your own career instead of big splashy doge headlines followed by desperately trying to rehire and hire new expertise when you realize what you've actually done.
You make a good point.
I'm skeptical though that 100% (or even more than 60%) of the workers in the DC offices are true specialists in agriculture vs. office workers who happen to do agricultural work. Certainly there's a set of institutional knowledge to be maintained. But the most committed specialists are going to be the ones who are willing to move to e.g. Ogden Utah, as the previous commenter mentioned. The slightly specialized office workers, being able to swap into some other role for ${BUREAUCRACY} are less likely to move and less likely to need to. There are people in Ogden and ${RURAL_CITY_[1-5]} who are able to do the support work needed.
However, as you say, the time scale is important and I did not really take that into account.
