Biggles, don't take this the wrong way, but you demonstrate well why such laws are required; to guard against the possible actions of those with the inability to understand the basic concept!
Please do not see this as a criticism, but as a statement of fact. If we did not have such laws it would clearly be a free for all. Now whilst I am sure you would deem anything you would do as safe and acceptable, would you be happy that all others actions, 100% of the time, would be safe and acceptable to you?
