The best protection against malware / ransomware, hardware failures or stupid accidents of your own doing is provided by regular backups, not by app store restrictions that don't work anyway for the stated purpose. I do not have SELinux/AppArmor installed, I can't remember the last time I installed an antivirus and it doesn't matter, because I have backups with file versioning going back for a whole year of everything important. My laptop could burn in a fire right now and I wouldn't lose anything. But then I don't remember the last time I had problems with malware, because I don't install random software from shady internet sources either. It's typical of software developers to solve social problems by automation instead of education. It doesn't work well, it never did.
