First, you're criticising fiscal stimulus in general, not helicopter drops in the original sense. Second, creating inflation is very beneficial when current inflation is below target. That's the point. Third, inflation harms holders of money, not those that have no money. It thus incentivizes spending and investment, which is why we have above-zero inflationary targets. Yes, hyperinflation is bad - which is why helicopter drops have to be used in moderation. But then again, that's true of almost anything in politics and life in general, so I don't see why that's relevant.
