I am saying it depends of the attack scenario. Privilege escalation is a big issue for servers and mutualized systems. On a personal computer this is the least of your concerns as your personnal data is more valuable than some binaries in your root filesystem. People are ready to get their precious data pwned or ransomwared but are afraid some process would get root access, this is backwards thinking.
