I would suggest that there are two benefits to having a UPS, only one of which (protection against short-duration power outages) you regard as one.

The other-one is the ability to shut down machinery cleanly and without undue data loss. The bit of your message that I did not quote indicated that this aspect is of less use to you (which is fine), but to many people this is the principal reason why they have a UPS.

(For completeness: surge protection is a third benefit, but that can be obtained by means of a surge protector as well, i.e. without a UPS).
