Doing what is most economically efficient is not always what's best for society as a whole. The bankers and deregulators that helped create the Great Recession were just doing what was most economically efficient at the time. Tunnel vision like that often leads to very huge negative unintended consequences. Doing what is most economically efficient readily contributes to the destruction of the commons, whereby all of us suffer in small and large ways.
Most strawberry farms won't be replaced with a Disneyland, they'll be replaced with just another shopping mall. As a counter thought, consider what would happen if you decided to sell off Central Park in Manhattan. It's prime real estate and a lot of folks could do some very economically efficient things with that land. However, it would absolutely gut the character of Manhattan and a huge portion of the appeal of living there.
Building a city worth living in and being a part of cannot be viewed in strictly economic terms. And what's best for the economy is not always best for the people inhabiting a society. Some level of balance should be struck.
