Where endeth the Castle?

According to the online news Quiz for the UK's Guardian newspaper, it will soon become illegal for people to litter their backyards. I didn't see the original article on this, so I don't know how they're intending to enforce/police the ban but it does make me wonder where the rules and regulations will end. How long will it be before the rule moves inside and houses themselves have to be kept clean, tidy and uncluttered? Unfortunately, it would still be too late for the Collyer brothers.
