PoE is awesome. My custom home security system is all CCTV PoE with a gstreamer backend running on four-core fanless linux box. Way to go. Complete control. No batteries, no wares spying on me, no personal data getting scraped by big guys. (Cloud connectivity sucks because I have segmented mp4s and jogging through them hurts but I only care for events after they happen, not while they happen.)

Poe is great for many things, but it’s not as efficient as direct connection (for both low and high power.)

That's pretty much stating the obvious. X is great for many things, but it’s not as efficient as Y.

Life is a balance between inefficiency and inconvenience. Throwing that statement in without actual numbers is just derailing the conversation.
