> There is gas and diesel - it is just expensive for everyday folk relative to how much money they can realistically make

Do you have first hand experience from the last ~month? (since everything has collapsed again)

Friends living there who are very, very well off can not physically get their hands on a single liter of gas or diesel.

I recently spent 6 weeks driving around virtually all of Zimbabwe, I have a pretty good idea how the country works (or at least, before the most recent collapse)

Currently in Zimbabwe. It's not an issue of affordability. The country allocates foreign currency to bring in fuel, there is a shortage of foreign currency and the government is struggling to bring in enough fuel to meet demand levels.

Exactly the same as when I lived there. We had the money, but we would queue round the block (even leaving cars unattended) waiting for the fuel to arrive.

No it wouldn't help. There simply isn't enough out there & quite frankly people would outpay "$5k on a passion project" for a stable supply.
