The really important question is whether or not at the Planck scale one finds that we are all one really, really big version of Minecraft, being played by beings that look strangely like turtles. All the way down.
Another really important question is just how much of the world's creative potential is devoted to creating meta-inventions on top of rulesets intended for something else entirely rather than, say, bringing about world peace, curing cancer, feeding the hungry, or just plain moving out of your mom's basement. Not that I am entirely without sin in this regard myself, but it is a sad commentary on the state of the world (virtual or not) that we appear to live in when solving vast and pointless artificial problems in a virtual reality is more appealing than tackling the real and serious problems that surround us.
The problem with things like feeding the hungry is all of the political opposition you would run into. Since the Industrial Revolution of the late 1800s we've had the capability of feeding, clothing, sheltering, and educating the entire world's population several times over. What we don't have is the political will to do it. Too many ruling elite would have to give up power for it to actually happen. That's the real obstacle.
Most armed conflict is also to the benefit of this ruling elite, who use such phrases as "ordo ab chao" (order out of chaos) to describe their interest in it. Wars are very profitable if you're a well-positioned sociopath, and playing two sides against each other is a great way to increase your power over each. It's the same military-industrial-complex that Eisenhower tried to warn us about, not that we listened.
The financial incentive related to cancer is that sick people are much more profitable than healthy people. A cheap, easy, one-time cancer cure (if there were such a thing) would absolutely devastate the multibillion dollar "cancer industry". The companies profiting from that would be just as eager to embrace such a cure as the RIAA/MPAA middlemen have been eager to adapt to an Information Age where the cost of copying and distributing a work is nearly zero.
Getting out of Mom's basement was easier in the past when good jobs that led to good careers with good pensions were available to anyone willing to work hard, which was when the USA valued and protected its manufacturing base, recognizing it as the real wealth and independence from foreign nations that it was. Additionally, it's not generally young women who are staying at home with Mama. They're showing the drive and ingenuity that young men used to also have. I'd recommend reading Boys Adrift by Dr. Leonard Sax for an in-depth explanation as to why this is happening, from grade schools that try to force boys into developmentally inappropriate roles (and then brand them ADHD when it fails), to chemicals in the food supply that have a feminizing effect on animals and humans, to reduced testosterone levels and sperm counts, etc.
These are all problems that we could do a much better job of addressing, with some of them being completely solvable. But for that to really get started, we'd first have to stop allowing psychotic sociopaths to have power and make all of the important decisions. It wouldn't hurt to also have a mass media that didn't use so many recognizable propaganda techniques, and/or a population trained in logic, reasoning, and introspection, considering these skills as basic as literacy. Until then, every starving person on the planet is basically a monument to how psychotic and fucked-up this civilization has really become.
