eli5 why we can’t collect energy from lightning ?

Saw lot of videos and it seems pretty easy to push wire to thunder clouds to make lightning hit exactly that wire. Why not put some sort of big ass super capacitor and collect this free power for sake of humanity?

One lightning strike only contains a few hundred kilowatt-hours of energy. Caps store something like a tenth of a watt hour per kilo, so you’d need a capacitor weighing roughly 2,800 metric tons. Hundreds of cubic meters, you’re looking at a warehouse of solid capacitors.

That’s all for the energy equivalent of one full tank of gas in a car. An entire building versus a $50 tank of gas.
