I agree. My setup is very much like the setup shown near the end of the article (the one that consists of a couple Synology NAS boxes and what looks like a few Mac Minis or other small form factor PCs). I have a file server with a decently large storage array and a few Raspberry Pis and other small electronic gizmos, some of which connect to my wifi, and some which plug into a PC via various cables (ethernet, USB, etc.)
The only thing out of this that consumes any amount of power worth mentioning is the file server/storage array. I haven't measured how much power it uses (I probably should), but I'm able to minimize it by allowing the disks to go to sleep and the CPU to run slower than when I'm actively using it.
I've never felt limited by this setup at all, but, then again, my home lab isn't really my main hobby.
