Ideally, sure, but then when we replace electricity sources we still have all the things we weren't able to electrify, and we're faced with scaling up something like this from scratch. We need the fastest path to net zero including things like cement and ships and long-haul jets and agriculture, and all that adds up to more than our emissions from electricity. Fastest path probably includes getting a head start on negative emissions.
