Batteries and concrete?
(OP)
I've always heard that storing a battery on a concrete floor will discharge it. Is this true? If so, why?

So, in theory, if you scrub your battery case clean, and maintain it clean, then there is no leak path, it will not discharge. Go ahead and set it on the concrete.
This explains why every battery set on concrete does not discharge. But, many have, so the phenomenon is real.
Now, before you pounce, this is what I was told by an engineer at an automotive battery manufacturing plant when I ask. I took his word for it, and am just passing it along. And, by the way, I am old school; I still set my batteries on a wooden block. I will set them on concrete for a few moments, but not for long term storage.

That changes my habits as to storage of batteries? Nope, like I said "old school". You know, just in case my ideas are off in left field!
Oh, yes. I now only use "gel cell" technology batteries in most applications, race cars, motor home, etc.

Leakage to ground is not going to be an issue unless one battery terminal is directly grounded, or several batteries are connected in series. At the high voltage end, leakage to ground might then be a factor, especially if the final voltage is fairly high.
In large high voltage commercial battery installations it is preferable to completely isolate the dc system from ground, and monitor earth leakage current. This will usually bring up an alarm if it exceeds a few milliamperes. The biggest danger of earth leakage currents are usually from electrolytic action and corrosion. If the leakage is serious enough to cause significant battery discharge, the wiring is going to be eaten away very rapidly.
Traditionally, large battery racks are made from wood. It is strong, cheap, and resists battery acid.
