T2 and ARM macs are thus entirely unsuitable for e.g. the antarctic research stations, as if one is infected with a virus/malware and needs to be proper wiped/reinstalled, doing a full disk wipe when you have no internet means you *cannot* get the machine back in a working state, even with offline USB reinstall media, because the T2/M1 needs an online reactivation. no internet = computer is a brick. (iphones and ipads already work this way.)
