Who told you that was no longer the case and where are you?
If you're in England, I think your source is getting confused between the CAA Act and the laws of Trespass. Even then however, you would not be immune from prosecution by simply leaving someone else's property when asked, even if you hadn't damaged anything. This is a huge and complex subject, but the bottom line is that you can't just land anywhere you feel like it (without the owner's permission) without also risking a claim being made against you, either by the CAA or the land owner, or both.
