@Ronnie Amiibo are just as much a 'fad' as VR may or may not turn out to be however. And yet they've managed to garner hundreds of pounds of people money. You're right in that you could put this to any product, but exactly, it's completely up to people how they spend their money and where they deem value to lie.
Why do you call the price for the tech laughable?
Personally (well, because I can't afford to), I'd never spend £1000+ on a cutting edge TV... but people do! And maybe that's the market Oculus is looking towards. The average gamer isn't the primary market.
(also Ronnie what's your PSN ID?)
