You're positing a scenario that shouldn't occur in the first place. Such a website should be on a shared or managed hosting service, or alternatively, there are companies that will, for a reasonable monthly fee, perform basic routine maintenance such as this on your servers.

If you want to completely mismanage a server you depend on for your livelihood, I can't stop you. All I can say is you're doing it wrong.

Running on shared hosting doesn't solve this and introduces a bunch of other issues, you still have to worry about wordpress installs or whatever.

There are a lot of poorly managed VPS out there, these would be better served applying security fixes automatically.
