I don't know about calling it a *bad* idea, but it's certainly not a *good* idea. Is there any sensible use case in which every IP-connected device in the world needs a globally routable IP address? Of course not. That's the reason why self-assigned link-local IP addresses were invented in the first place and those work *great.* The idea that it's necessary, or even desirable, to have a thousand globally unique and routable IP addresses for every man, woman and child on the planet is just patently silly.
Yes, IPv6 is overkill. What's more, it's actively user-hostile overkill. A great example of how is the convention that any arbitrarily long series of zeroes can be replaced by two colons in a row. Does that make IPv6 addresses easier to read? *No.* It makes them *shorter,* but it makes them considerably *harder* to read and compare to one another.
If we lived in a world in which IPv6 were a thing *and also* no person would ever again have to manually assign an IP address to anything, that'd be different. If two computers want to identify each other with strings of numbers and letters that read like half a dozen license plates stuck together that's none of my business. But that's not how it shakes out. In real life, IPv6 addressing is just as manual a process as IPv4 addressing was, only a lot harder because now you have to learn to read these long and baffling designators that make hardware serial numbers look downright colloquial.
"With IPv6 we can assign a unique address to every proton in the observable universe!" Great. Except we can't *easily* assign an address to anything at all.
