Current problems of VR are - no realistic graphics, no option to protect your mind in context of differentiation of objects in it with context to real life, eyes subjected to light source which consistntly cant take it much and also it has other technical issues. but they are issues of today, in 5 years from now on they wont be.
Thing is if you have happy childhood, happy adulthood, you have literally nothing to gain from VR, not even gameplay wise because that would just irritate the hell out of your brain and eyes. But if there are some suffering people out there (people who are under trauma, who are burned out, who had lost people etc) in such case, it can be therapy for many. I know it could be therapy for me.
