Money multipliers are a pretty well understood idea. US gov spends a dollar, it gets used to buy something, the seller uses it to buy something else, etc. GDP is the value of goods created, and a single dollar used multiple times can be counted many times. It's a bit naive to make things are so simple. A great example is a huge toy doll, 100 stories tall. Imagine the engineering milestones that would be reached by such a project. Imagine the huge number of people employed! Those are distracting from the fact we don't need huge toy doll. Also, you'll never hear a politician point out that the dollar spent has been taxed, and would have not incurred the dead weight loss of the taxation process had it just been spent and re-spent.
