Scott Cleland has a good piece in his "obsolete law" series demonstrating why it is important to get rid of outdated legacy regulations.
His blog discusses how Google declined to offer phone services in connection with its touted fiber project in Kansas City when it discovered how costly compliance with the existing rules would be. Not worth the incremental cost in Google's view.
I don't advocate saddling Google with legacy telecom regs, but I do advocate -- as does Scott -- getting rid of them.
