Agreed - Even now we're talking a about spending a ballpark $200-$500 for a VR headset, plus $1500 on a computer to run the software (that a lot of us already have). That's not a trivial amount of money, but it's hardly outside the reach of anyone in the developed world.
Consider that computers, microwaves and maybe even TV's started at tens of thousands of dollars - and that's before adjusting for inflation - and it's hard not to say it's already stupidly good value for money for an entirely new medium.
