"The burden should not be on people to prove why they should be allowed to do something, but on the authorities to prove why they shouldn't. Thus, why shouldn't people be free to hunt, or smoke cannabis, or build an extension to their house, or travel without an identity card, or read pornography on the internet, or adopt children? There may be reasons to prevent any or all of these things, but the restrictors should be the ones who have to make their case."
