It's only insurmountable if you never try it again. There is a learning curve where some people feal quite sick at first and then slowly get used to it. You can mitigate this with "training wheels" settings in the experience like blinkers, cages, hiding the VR body, and alternate locomotion schemes like teleporting. Some people even swear by just setting up a fan to blow air on them while they're using VR.
