There's your argument for Bitcoin. It cannot be planted by anyone, like tulips. Its supply cannot be increased arbitrarily. Tulips, in fact, could be a bit more complicated. Bitcoin is quite simple that way. Spent electricity is stored and traded - and is a good yardstick to measure other things, etc. etc.

wouldn't storing electricity mean that you're able to take some out of storage & use that stored electricity?

I don't see a way to turn bitcoin back into electricity. One could exchange bitcoin to fiat currency and then buy new electricity(created from a different source) but that's not really using stored electricity.

That's true. It's a verifiable "burn of electricity". The only upside to the burning is the verifiability. If there was some other way to generate this verifiable scarcity of something that we all agree on (electricity is kind of universal, that way), that would be better - obviously.
