Do you have any idea what you are talking about? Operating and maintenance expenses dominate all aircraft expenditures - "already there" is completely false. Putting these aircraft in the boneyard and writing off the R&D expenses is the only logical answer to "peaceful use."
An F-35 can get somewhere "quickly" when it's ferried there by a fleet of tankers and logistic support - but at that point, you just fly the C-130 directly to where it is needed.
No single day makes the difference in any of the situations you've proposed, and no operation to get a payload-laden F-35 anywhere it needs to be is organized in a day.
> Spend a billion dollars to make these devices, de-commission the F35's from the task of bomb dropping, paint it pink and turn off its stealth, and have them drop the cluster medical kits immediately.
There's no expense that justifies keeping these aircraft in operation for any peaceful purpose. Basically every modern cargo or passenger aircraft is better at the tasks you're describing and can do it cheaper.
Taxation is inherently backed by violence, so it's amazing how you can casually just suggest "spend a billion dollars" and not see the cognitive dissonance you're spewing.
Accomplishing all of this random humanitarian shit costs money (a proxy for human labor output), money comes from somewhere, and it isn't going to be given to your causes voluntarily.
