Well, you're completely on point regarding events lasting a week. I'll leave off BTC, as I reckon my dissent isn't much use to anyone but me around here. Fuel will last weeks, even months, well stored, but will not last years, and that's where I was aiming.

The kind of disruption under discussion will last a lot longer than a week or two. I'm looking at disruption of food supplies that began this year and will get worse for decades. Should the coronavirus be as bad or worse than the media is fearmongering, that impact will also last decades. Economic disruption, as well, even without the other two exacerbations, will also persist for the foreseeable future. None of the obvious vectors of disruption will be over in a week, AFAIK.

Be well. I am confident you have the practical wisdom to manage any of these circumstances.
The most important asset you can have during such times is practical knowledge and being willing and able to do the work. I reckon you have that.
