Pretty much everybody wants to be able to use a phone on the go. However, if cellphones made 90% of people nauseous after a short time just from walking around with them, they wouldn't be that popular.
Nausea from VR is not some sort of intrinsic property, it's due to a number of physical factors, many of which can be solved technically by better hardware or by the design of VR experiences. It's not going to be easy, but it's not an intractable problem.
The difference between the VR we have now and the VR we had in the past is that now there is momentum towards moving the technology forward. You have multiple companies competing to develop hardware. You have many developers working on VR experiences and learning what does and does not work. You actually have people buying these things and using that software.
