chornedsnorkack If you would like ticket prices to rise sharply and ensure that everyone is willing to pay the higher fares, then I am sure the carriers will implement your idea.
Since ALL the carriers in the world operate overbooking, then there is clue about human behaviour in the world.
By the way, this subject has been debated in PPRuNe countless times and if you search for the threads, you will get all the permutations. Overbooking was something of a problem 20 years ago when it had to be calculated by hand and updated once a quarter or so. But the computer hard/software available now is remarkably clever and learns from each and every flight. (I sit to be corrected)
