Consumer demand doesn't necessarily equate to success or profit for the inventor. Say you're a one man start up and you invent something really cool in your garage. You start marketing it, get a bit of leverage and sell a few. It's going great, you've got some orders, get some money from an investor, you've got a proper workshop and are growing nicely. Then Samsung or Apple see what you're doing and think it looks cool. They get their factories up to speed and throw a few million dollars into marketing (that you don't have needless to say) and before you know it they're selling millions. Everyone wants it, consumer demand is off the chart and no-one cares a jot about you in your workshop any more because Apple and Samsung can make the thing cheaper and get it to consumers faster. So, it made it to market, there's plenty of demand and yet where's the incentive for you to do anything when you have your next great idea other than go and get drunk in a ditch because you've got no desire to get screwed over again? Yes the consumer benefits from cheaper devices but they also benefit from great people having great ideas and being incentivised to do something with them because they know they could get a reward. And that's before we get into talking about how we do want to encourage failure because if we try 1000 long shots, even if 90% of them fail, we'll have more great stuff than if we try 100 things and half of them work out. research risks benefit the consumer in the long term.
