You’re literally executing random shell scripts by strangers as root.
You're literally not doing that. Escalated permissions are needed for installing dependencies and installing the resulting package, not for building. Just try running makepkg as root and see what happens.

Not every PKGBUILD contains a .install file. So again, it is not inherently the case that you’re "literally executing random shell scripts by strangers as root." slackness has it right that most people probably don't read the install files, but it seems to me that their prevalence in the AUR is overstated here.
