I heard an interesting podcast a little while back that conjectured the typical way to get inflation going (so-called "helicopter money" to the spending population) is far and away the least predictable way to do things. Specifically, the speaker argued that compared to large banks and investing entities, people might do things like pay off debt or save the cash for a rainy day... neither of which are inflationary.

That isn't to say that handing out wads of cash wouldn't eventually lead to inflation, but that the systemic lag and second-/third-order effects might make the process so unpredictable that by the time inflation begins to tick up, the central bank would have no way to provide effective control.
