What specifically is not sustainable?
As I see it you're basically arguing for less focus on innovation. Skiff failed as a business. To not waste resources would mean it had to never have existed in the first place. That means you need to limit the desire of investment in risky or innovative ventures as most of those will fail. When they fail the resources used for them are wasted. This is because if you limit the ability of companies to exit to recoup some loses then you increase risk for starting a company. It also doesn't prevent waste in any way since the existing large companies (now even larger due to less competition) can still internally make and kill products at will. Or just do things very inefficiently.
