Over time, perhaps. But we don't have time. Where are the low-methane cows? The low-carbon flights? When will cement pollute less? Why are we still generating 61% of power with coal and gas [0]? Part of the answer to all of these things is that there is a lot invested in maintaining the status quo. Airlines getting away with tax-free fuel isn't a technology problem. How long, realistically, until any significant proportion of current meat eaters switch to lab-grown meat or other alternative? And how much political capital will alternatives need to accumulate to take on the meat industry?

Sure, technology can help with any of these problems but it'll take forever as long as governments only pay lip service to wanting to change things.

I think you're both right. I don't think we'll get much mileage by limiting consumption via legislation, but I do think subsidizing industries like renewables and green research (and phasing out dirty energy subsidies) combines policy and technology to get us there faster (in time?).
