Yes. I used to go to the UT surplus property auctions in the 90s when they still had computer equipment and there would be lots containing twenty or thirty compact Macs.
They were everywhere.
Making the repair parts more accessible would cut down on the amount of cannibalization. I think that would be a good thing. It seems like the two parts that are now unobtainium as "new" parts are the adjustable inductor on the analog board, and the CRT. Apparently the same CRT was used in a bunch of security monitors, so you'd think there'd be a pile of them out there somewhere.
