No quotes; no private transactions by anybody required to file Form 3's & Form 4's; directors to take personal liability, without a corporate veil - for anything registered with the SEC which doesn't report.
Once you're registered, you should only be allowed to de-register via a vote by non-insider shareholders, or via bankruptcy (which should be automatic grounds for deregistration, except I guess for Ch.11).
