Given the hundreds of thousands of listed companies you can find examples of anything, but there's nothing inevitable about companies being run purely for short term concerns. Not every company is run that way, shareholder theory or no. Plenty of listed companies are capable of extremely long term investments.

Even when it doesn't the existence of failure modes in a system doesn't invalidate the entire system. All systems have failure modes, they need to be evaluated as a whole.
