Sure, but you are arguing for short-term spending vs long term capital investment. Basically you are arguing that you don't need to get more sleep, you'll just have a red-bull tonight. So the red-bull is better than getting more sleep in general. If you take all the money (100%) from people who build and make things and give it to people who don't have jobs to spent, in the short term things will be bought and everything thing will appear stimulated. In the long run your entire economy will collapse as your capital base erodes. The basic Keynesian error is to not distinguish between purely consumptive (why don't create jobs to build ships, fill them full of gold and new technology, and then drive them into the Pacific and sink them?) and productive goods which actually build economic wealth and raise the standard of living.
