Thanks for reporting! I am not using tramp regularly and I did not think
about this use case.

I can easily make a change that always garbage-collect non-local
documents without trying to connect to remote server. This can be one
solution of your problem. However, I am not sure if it is the best
solution.

May I know more about your use cases? Do you frequently open large
remote Org files? If you do, trashing their cache may not be optimal.
Maybe we should better make this a user option?

Or we can go a different route and just not garbage collect remote files
until cache gets too large.

WDYT?

Best,
Ihor
