As DanielBMarkham said in the top post, the problem is that governmental offices need to look like they are productively creating value. Getting out of the way doesn't get a bureaucrat a career advance. The government way would be to use tax money to create a startup development program, so that the administrators can point to successful outcomes from it and take credit. Never mind if we'd have more successful startups without a program at all thanks to lower tax overhead. Government cannot create such an outcome because government is composed of individual administrators all with their own self-interest. Government cannot remain idle even when remaining idle is the best solution, because each civil servant needs to be seen as Doing Something.
My state, New Jersey, has as part of its income tax return a moderately complicated form that amounts to a $50 rebate credit against property tax. Wouldn't it have been infinitely simpler to just lower property tax by $50 in the first place? Of course. But the extra paperwork creates visibility that They Are Doing Something About Our Taxes, which perception is far more important to the politicians than actually doing something about taxes.
I'm vaguely reminded of Internet Explorer's "enhanced security" stuff. IE looks more secure by emitting "we protected you!" notices all over the place, than if it had never been designed with such inherently risky OS integration in the first place.
