Do they ever learn?
Remember the news story not long ago where driving test appointments were being block booked and then sold on at a huge profit?
Not only do gov.uk not learn from a technical point of view, but they don't learn from a legal point of view either. Shirley it's easy to make it a specific crime to profit from this sort of carry on. That wouldn't actually stop it from happening because there will always be somebody willing to take the risk of prosecution. What such legislation would do it make it easier, cheaper and quicker to prosecute. Which would be better for the public purse, but also more and quicker prosecution would then present more of a deterrent.
Oh and whoever mentioned event tickets earlier. The government keep on telling us they are concerned about ticket scalping but when challenged to do something about it they say it's complicated. No it isn't there's an easy start, just make selling tickets for more than their face value a crime. Oh and yes that does mean that charging an "admin fee" on the sale of tickets would be illegal. And so it fucking should be. I get tired of seeing a list price on a ticket and then learning there's several pounds "admin fee" per ticket. If you're ordering online how can there possibly be an admin fee per ticket? Maybe per sale (although I'm not even sold on that) but PER TICKET?
Again this wouldn't stop people selling on tickets at inflated prices, but making it a specific offence would make prosecution easier and therefore make it more of a deterrent.
In short legislation will never stamp out this king of shite, but it can reduce the problem
