I often see posted about how covering a relatively small area in a desert with solar panels could power the world – but transferring that energy is too difficult. Why can’t we just use that to charge batteries and ship them places/ everywhere?

Because everything uses energy.
Moving energy requires energy. Batteries are heavy. Heavy things need trucks. Trucks need fuel, roads, maintenance, drivers, etc. And at some point you spend more energy moving the batteries than the batteries store.
