You have the same issues with gold also. Although it's very unlikely gold would lose most of its value, the price of gold throughout history has fluctuated greatly:

Even for assets with industrial applications, there's a risk that it may be replaced with something else, or made cheap (e.g. synthetic diamond; aluminium was a precious metal before electrolytic production; asteroid mining?).

I agree with your comparison of Bitcoin to tulip bulbs. Just because Bitcoin is used as a store of value doesn't mean it's wise.
