I can't say I agree. Apart from the fact that your whole post reads like you are a pioneer salesman, most consumer-grade electronic gear is ALWAYS going to get superceded by development in technology over time. That huge 38" rear-projection TV that you bought in 1994 after the salesman told you it "would last a lifetime" certainly hasn't either. The other issue I have with your suggestion is your:

Top quality, little-used

If anything is 'little-used' then it will almost always be a BIFL. My $1.98 clip folder that I use to file tax documents once every four years is BIFL by that logic. Never mind that this clip folder is just another piece of made-in-china junk. Little use keeps it in check!

(4) The fact that some states like CA banned them makes them all the more coveted.

Banning a film for ultra graphic content will make it coveted and cult in status. Banning a mass-market consumer product in some states means people will just buy something else in a market saturated by choice.

And yes, OLED, or whatever the next breakthrough is in display tech, will make the silly consumer who paid $7000 on Amazon for a dated television feel pretty stupid...
