To be perfectly honest, if someone lands without being invited, the landowner CAN, if he wishes to stop aircraft landing, charge what he likes and I really don't believe that a landowner can be at fault in the event of a subsequent incident. If an aircraft arrives unannounced, gets charged a disproportionately high landing fee for not being welcome, and is also asked not to return and then hits the hedge on the way out, I think most judges would hardly put the landowner at fault!!
