The Terminal / Whonix Konsole and specifically root on Terminal granting absolute power over the system is I think a very well understood and accepted concept even for the average user.
I can come up with such one liners as you mentioned. No need to post them here, someone might actually run those by mistake.
But a bitcoin wallet easily allowing the user to run any script that affects the whole system isn’t a naturally accepted behaviour. A bitcoin wallet should have absolute power over the content of the wallet, not over the rest of the system. That should belong in some kind of developers addition perhaps, not on the mainstream software.
Isn’t that the whole point of Apparmor and similar restrictive methods?
I am not aware of any other GUI application that (will now be) installed by default in Whonix that has the same power with the same ease (where no software download is expressly done by user, no obvious installations etc).
