It is all psychology. If someone believes in an idea enough to invest in it, then others are much more likely to invest in it. So, an idea with resources committed to it is worth more than one without. The ironic part is that the idea itself is not what is invested in. Often there is an attribution error where we hear that "he's making X, so we should make an X clone." However, the important thing invested in is not the idea X, but instead X+the team+the business plan. Of course, the media often does not mention the latter two.
