I have thought of this too. The problem though is that an idea doesn't really have much value.
Many people thought they had GREAT business ideas , but even though those "GREAT" ideas did get turned into businesses ,they became worthless businesses.
For example the .dot com era...sure we look back on it now and laugh that these companies got so much funding..but people with money obviously thought they were great business ideas...who would spend millions on an idea that wasn't GREAT?...

Lot's of examples on that list of the companies , and we have similar companies around today. Trying to do similar things.
You don't hear about business ideas being sold often. This is why people say they are worthless.
If one doesn't take action to create something , there's nothing there.
Would you buy a business idea yourself?...
Another thing is that people thing you need some novel idea to make a great business. It's really in the execution .
McDonald's was not the first hamburger place in the universe..but the WAY they ran the business and systems they built led to massive success.
You see this all the time , even nowadays there are lot's of new burger chains, pizza chains,etc.
I think people think too much that they need some "genius" idea rather than how they are going to realistically execute on the idea and make a profit.

The problem I see with the follow your passion crowd is that it creates all of these companies that are big on ideas..but don't have a real plan to make money from those ideas.
Many startups today are actually apps and 99% of apps apparently don't make money..

"for all the apps released this year, 99 percent will lose money. This, said Gartner VP Ken Dulaney, flies in the face of what you would expect. In fact, Gartner predicted that by 2018 less than 0.01 percent of consumer mobile apps will be considered a financial success."
I'm sure at least some of them are passionate about their ideas...but that doesn't put food on the table.
