but the government can't cover every angle.
Oh yes they can and they have. For every positive change they have made they have a counter negative change. Basically covering their backs in all corners so if /when things do go wrong they have someone else to blame. It could even be argued that it's a form of entrapment via confusion and misunderstanding to rake in even more increased fines. It's all about money and the economy feeding back to government right now hence the estate agents. Lots of tax revenue in the housing market.
