That's precisely why I run a PC NAS once a week for a few hours as a secondary NAS.

"Any form" is a vast range. Between a full desktop-like PC purposed for this, with an average idle power consumption of 80W-100W and a small system around a mini-ITX motherboard which will idle at around 15W-20W, there's quite a span.

Other than that, if this is a NAS for personal or small business use, it may not (in the case of personal, most surely not) require being on 24/7, but maybe only a couple hours a day. You don't need to leave it on. My personal NAS is built around a mini-ITX motherboard, draws about 20W when "idle", and I put in in standby most of the time (where it draws only 1W or so) and wake it up with WOL when needed.

You do need to be careful about power consumption, but saying all PCs are inefficient is misleading. I have have been using the same Intel i3 system as a home server for about 12 years. It idles at 12-13W from the wall, and quite a bit of that is taken by 2 3.5" hard disks. Choosing a suitable motherboard and power supply is a big factor. Some motherboards with massive overclocking potential can have a horrible idle power draw. Some power supplies seem to be designed with no regard to their efficiency outside the range laid down in the 80PLUS spec.

My experience is the exact opposite. I am still using a ZFS pool that I created 15 years ago. The disks in the array are now more than an order of magnitude larger, but the pool and my data has persisted all this time. I have backups, but have never needed to recover a byte of data from them. I have replaced old small disks with new big ones, replaced sick/dying disks with healthy ones, and replaced outright dead disks with new ones. Pool always up and available, data intact.
The difference may be the operating system. I have always used Solaris or a derivative. ZFS was designed on - and for - Solaris.

I do agree though, that just using redundancy (whether ZFS or some other RAID scheme) is not equivalent to having a separate backup.

Well, compared to a relatively simple ARM processor optimised for super low power, even an i3 is quite a power hog. For comparison: the Qnap NAS I have consumes little over 7Watts max. including the hard drive  according to the specs. But I'm sure this number is too high as I put a low power (2.9W idle), 5400 rpm hard drive in it.
