The problem with existing research is that it simply isn't that open to new ideas, particularly once funding streams are in place (because shifts in funding mean job losses, institutional impacts etc).
As you are pointing out, VC's often see monpolies as something to disrupt. So you'll take the taxi industry for example. A govt sanctioned monpoly with horrible service and low insurance limits. They'll make a play with something like uber.
Hotels -> airbnb / VRBO
And the list goes on.
You point out how VC's don't focus on short term profits. While I would agree, some however would argue that VC's should focus MORE on short term profits. I personally think too many money losing businesses are subsidized for way too long with VC money. In biotech that may be a good or necessary thing, but personally think this longer view is a bit of a negative.
