If you think that there is even the slightest chance that the power cord could get tripped on and yanked, you should not buy the macbook. The first time someone trips on the power cord, the usb-c cable could bend inside the port and damage the only way of charging the computer rendering it unusable. That is why Apple designed the magsafe chargers for all other MacBooks. If you damage your charging port, Apple will not repair your macbook for free even if you paid $200 for Applecare. You will be completely out of luck.
