They already sell phones over 1k that are expected to last ~4 years. You'll need to tag another zero or two to that price to incentivize manufacturers.
So what if power requirements increase. It could quadruple and now my battery will only last twelve years? There are plenty of other things that will start failing before then.
I'd take it if it was a reasonable price, like 1k, and if I could just swap it into new phones every time I upgraded.
The problem is, power requirements tend to increase as computation power increases. And no doubt battery tech will improve in those 50 years.

They could do it to gain market share.
