My point being that a little conflict with my wifi might be ok as long as it's a fair transaction. If I'm freeing the spot for sale and get payed. It would also replace bureaucracy with economics instead, which should be good for optimizing utilization.

The main difference compared to carrier sense is that I'm suggesting a competition based negotiation, not cooperation based. Instead of waiting for a free spot, you buy the spot.

If the unlicensed spectrum is a commons, the problem with uncooperative commoners like this LTE-U thing looks an instance of the tragedy of the commons. In a sense I'm suggesting a form privatization.
