Whose body is it anyway? DC Government and tattoos

Personally, I am not a big fan of tattoos, but I am also not a big fan of nanny-statism, including this example:

Some popular impulse purchases — tattoos and body piercings — could soon become less impulsive if District [of Columbia] health regulators have their way.

A mandatory 24-hour waiting period is among the provisions included in a 66-page package of draft regulations governing the “body art” industry released by the city Health Department on Friday.

So the city government wants to take a more active role in adults' choices over their own bodies? What could possibly go wrong? Besides, it's not as though either tattoo parlors or potential customers could go to Virginia or Maryland or to a hack in the underground economy.
