The root of the problem is sudo, and su more generally. This derives from *nix, or mainstream versions today, requiring a super user, a manifestation of the problem with monolithic kernals. A microkernal may be a stepping stone to improving this but even this is not a solution. The only solution is no kernal space, no privileged user(s), all processes negotiate independently with each other.
No the root of the problem is the large attack surface systemd is creating by tightly coupling a ton of tools together, I agree about the microkernel idea completely though.
