But I could imagine, it doesn't only kill the roots, but all microorganisms around them as well so you'll end up with dead dirt instead of a proper soil. I also wonder about the energy footprint for heating that much water... My intuition screams "far too much to be a reasonable scalable alternative".

For weeding pavers I don't care about dead soil. It's soil that is cracks between pavers and I sort of wish it wasn't. I think the steamer is at least partially a flash boiler, so energy use isn't high. It isn't huge amounts of water it needs to boil.
