This has no relation to whether something goes to zero (or practically zero). Political influence? Sure. But I don't think anyone expects D.C. to bail out Bitcoin.
> A company has a "single point of failure"
Companies trade after bankruptcy. There are stubs, practical and theoretical, for companies improperly wound up going back decades.
Even if a state says "XYZ failed to pay franchise taxes and is now inactive," a shareholder can sue the former directors, holders of proceeds from the company, et cetera. (Company "ownership" is de-centralised and ambiguous, a fact that becomes uncomfortably clear post mortem.)
Colloquially, we call "practically worthless," i.e. where the cost of valuing something is likely more than it's worth, zero.
