Nope. It encourages filler and padding to reach a longer gameplay metric. Quality should count above quantity - a 2 hour super-mega-ultimate experience is worth the money. Heck, how many VR devs would have made any money at all if users could get a refund after two hours??
There's a large difference here, however. There are plenty of PC indie games that are less than 2 hours in length and for most part if the buyer found the experience enjoyable and worth what they paid for it, they won't ask for a refund.
The problem with VR right now is that the experiences are not only short, but they are in many cases highly over-priced for the experience that they provide leading to consumers not feeling like they got their money's worth from the experience. This then ultimately starts to sour them on the whole VR thing making them less inclined to purchase future VR titles. And that's just for the actual "good" titles. There's also plenty of VR shovelware on Steam.
That's a problem that VR has to deal with. It's expensive to make feature (story, experience, presentation) rich VR experiences and the user base is still really small. VR titles are thus short (low development funds) and priced extremely high for the amount of content and experience (from a user POV) in many cases.
It's unlike most indie development in that it's harder to, say, make sacrifices to graphics quality in order to boost the story and game experience thus reducing development costs while providing a rich and entertaining gaming experience. And the small user base means that it's hard to price your title appropriately to the level of content and experience provided as you want to try to recoup your investment.
Ultimately is it better for the user to feel satisfied with their purchase or for them to feel unhappy that they are stuck with a purchase that didn't provide content worth the price attached to the product? Which if they are unhappy means that they may then be less inclined to invest in that genre (VR)?
While there is abuse, people that feel a less than 2 hour title was enjoyable and worth the money almost never claim a refund for the title.
Also, people that habitually abuse the refund policy get flagged and lose their ability to claim automatic refunds.
