Not trying to get into a debate about security screening, but the "ticketed passengers only through security" rule is not to prevent evil doers from getting airside. It is to expedite the screening process. How long would it take if every ticketed passenger brought their spouse, kids, parents, etc. to see them off?
If an evil person wants to get airside, they will just buy a ticket. I don't see too many people using the refund game to get airside, plus I would think airlines might catch onto an individual who constantly buys a ticket, checks in, then cancels.
