I'm glad you find it interesting! I like the way you phrased the question, that's precisely what I'm trying to get at.

To clarify the thought experiment, 1 bond gives you $1 per year in real terms forever. If you buy 2 bonds, you get $2 per year, and so forth.

In other words, if you could invest in a different asset that (1) lasts forever and (2) has a certain rate of return, what yield would you require such that you would consider selling your bitcoin?
