Everyone has portal powers!

Putting myself in the game as if it were my reality. Was just thinking about how everyone has the ability to create their own portal, including NPC's. I would think everyone would just be fat and lazy. Roll out of bed and make a portal to go to the kitchen. Open a portal while using the toilet, to grab a drink.

Wouldn't even have to go into a restroom at all "with proper aim and portal placement" one could potentially, open a portal to the restroom (right in front of a toilet) and just wiz away, while "shopping" for a new sword from home, with a different portal.

Just think all the thievery that could be done, all the mischievous acts. Your bed can be the toilet for, well... potentially everyone lol. Wake up with a face full of piss!
The duck you just slaughtered for dinner. Turn your back and *POOF*! Someone else's dinner now, maybe gets stolen a few more times. Thieves stealing from thieves. All the endless possibilities!

I think that eventually, people would just be on guard 100% of the time. Waiting with a sword in hand, waiting to hear that portal sound, ready to slice an arm off... or slice something else off! if the person decided to make your dinner table their personal toilet.
