thinking a lot about optionality. it's a classic topic of bitcoiners, and with good reason. Taleb has spilled much ink on the subject, and in a productive way. it's a shame he acquired an allergic reaction to bitcoin.

bitcoin is the classic asymmetric, huge upside, little downside, option of them all. but what else is out there?

I would assert that owning and training in the use of firearms is a hugely beneficial asymmetric option. that's the whole "better to have it and not need it, than to need it an not have it" thing.

what else is out there that belongs in this category of asymmetric options?
