ELI5: Why is there no tall buildings that use lightning and move it to an electrical storage place, then use it to cut costs on electricity?

There are two big problems we face here.

The first is that lightning is unpredictable - we would be investing in a system that might occasionally help, but equally might do next to nothing for long periods and overall end up costing money to maintain without generating many gains.

The second is that we just don't really have the technology to capture and store that amount of electricity quickly enough. Those car batteries that take 20 minutes to charge with a fast charger? We are talking about needing a way to capture and store multiple times that amount of energy in a fraction of a second. The current technology we have just doesn't work that quickly.
