There were posts on 4chan PRIOR to the massacre that said exactly what you just said. I.e.: that the motivation was entirely monetary. Since the posts predicted a mass murder in Vegas before it happened, I don’t know why they haven’t been taken more seriously.

it's called the "high incident project". they want to make the american public think that places with extremely high security aren't safe. they are trying to create more regulations. you will see laws proposed within the next few years to put up more metal detectors and other security devices. media and politicians will be saying places with lots of police need even more police. i can't guarantee anything will happen tomorrow but las vegas is on their minds.
-johnif their plan is successful state of nevada will pass a law in the future making all casinos have mandatory metal detectors and backscatter machines. soon after a federal law will be passed to put these machines in universities, high schools, federal buildings, you name it. osi systems and chertoff are the main producers of these machines. sometime around 2020 chertoff and osi will merge into a single company. after they merge the owners will sell off all their stock and make billions in profit. mr chertoff has been in contact with sheldon adelson. mr adelson will become a huge sponsor of these machines and he will be the first to put them in his casinos when the law passes. this is my last message for now. don't expect me to return anytime soon

Sounds to me like a plan to convert Las Vegas into a ghost town with tumbleweeds rolling through the streets. After all, who would want to go there if such changes are made? We have to fly, but we don't have to go to Nevada.
