I'll try: The charter governs the relationship of the company to its investor. A share of stock is a contract between those parties. The charter controls what the stock "means" no matter where it trades.
So long as a company adheres to those principles, it doesn't matter if an individual investor can obtain their shares via ShortTermScumbags.com or the like. Having investors who are along for the long haul is a nice-to-have, not a must-have, since the goal is long-term focused companies which will naturally, via its principles, eschew reacting to short-term trends in share price.
