Maybe I misread, but I think the OP pointed out that it could be done with today's technology, not that it could necessarily be done cost-effectively today. But batteries are improving and their costs are coming down, so it's certainly possible to predict that it'll be possible at some point in the not-too-distant future. When that happens, people will be compensated because it makes economic sense, not because they are subsidized into an un-economic activity (though that could happen too, but I don't think that's what was argued here).
