Most wall outlets if they are a frequent use location only last a a handful of years before they start to get loose and maybe a decade before shit just doesn't hold at all.
A plug that you plug something into once or twice ever and leave it in can basically last forever.
I would argue that you are much more likely to break the cable physically by constant unplugging and replugging.
Or wear out the wall switch.
I have never heard of someone having to replace their wall outlets due to wear and tear
