I like the idea of owning land, not a fiat house. I would prefer someplace that does not have any building codes or where I could hide a small house. Perhaps investing the energy into a house that could last a very long time and provide some heating and cooling like an earthship.

I want to invest my energy building soil and growing healthy food. Doing some permaculture to make this land paradise for generations. 

I would rather have a little bitcoin and this property than a bunch of bitcoin. Both approaches seem good though, us permies will sell quality food for bitcoin. I may have to abandon if things get bad, but I keep my knowledge. If you are worried about needing to flee a government then focus on bitcoin and mobile infrastructure. I would still want land if took the second approach.
