There actually IS an "internal" value inside every bitcoin and it's the amount of resources (computers/miners/electricity) to build its block. As time goes by, the aforementioned "value" will rise because the difficulty to build one will be greater and the block reward will be halved.
By that argument, anything that required lots of resources to build, and cannot be easily replicated, should be worth as much as those resources, and gain value with time. But there are many obvious counter-examples to this claim. There are many old abandoned buildings that cost millions to build, may cost even more to build today, but now have negative value -- namely, the land is worth less with them on it than without them.
IMHO, your example fails to represent a meaningful and robust argument. Bitcoins are not getting old, nor they fall after not taking after them after 60y. Besides, there's a story about a Real Estate bubble that's been rolling around the news...

PS: I like your trolling. I like to do it myself sometimes
