Its a cool thought but the problem is that no teleporting with items would be very very hated.

1-lets just say you want to go and sell some hard earned items you worked for, knowing that people do that, outside of shops, people would set up some kind of camps, waiting for you to arrive. It would cause a lot more problems for staff because people are unhappy, could be avoided if the attackers are stupid though.

2-Its a massive hassle. Having to put all items away before tping would just be hated, it would likely make teleporting useless as no one would use it.

3-it also adds many risks, losing resources, money, time, buildings etc etc

Overall, cool thought, adds more realism and less command/staff operation. But it would be HATED (Or so I believe)
