I don't agree with you. For one thing, I think there's a false economy in penny-pinching on a building that you might otherwise use for literal centuries. But I also think that it's at odds with the type of government you should want to have. Even if you think that it would have no effect on the type of people who are willing to work there or their psychology as they work there, a government that is of the people must have a dress code because it must be among the people. The government should not set out to make your city worse before they pass a single bill just by being an eyesore.
