Depends on the price. Thanks to limited liability, WeWork share can never be worth less than zero. And just liquidating their existing office supplis is probably worth at least a few thousand dollars. But, of course, you'd have to pay off creditors first.

If WeWork lists and doesn't go under, and assuming even a weak version of the efficient market hypothesis, the price their shares trade on will be about 'right'.

Agreed. Though in the developed world, inflation is usually the bigger worry. (Unless you buy inflation indexed bonds.)
