It's not like the US government's current systems have any sort of robust security in place. Centralization will hopefully incentivize this effort.
Because it's not permitted by law.
You are not allowed to use data collected by the USG except for the purpose that it was collected for [1].
Obviously the law doesn't matter much right now and that's why the USG is pursuing it (and due to a lack of security; leaking it straight to other countries).
Or in other words, do the exact opposite of what DOGE is doing...
there are as many reasons as there are employees of DOGE. i'm not sure why you would trust them to do anything in a secure manner; they certainly haven't earned it.
