There was existing, alternative tech that was a perfect substitute: unleaded fuels. There was no economic loss and no loss of choice (unleaded is a perfect substitute for the vast majority of drivers). Clearly the same is true of ozone depleting chemicals. There are viable substitutes that were created by technology. In other words, these were absolutely technological solutions. I think these examples do point to something important: the funding and incentivizing of R&D and tech.
