Not sure where you’re coming up with this - the average modern gas stove is expected to last 13-15 years [1]. Obviously there are exceptions but we can expect 95%+ of this infra to be replaced in 20 years just due to equipment failure. Seems reasonable to expect that effectively all gas stoves in the US will be replaced at least once in the next 50 years.

> great political and personal cost

This assumes that installing new gas infra has no cost. It also ignores the long term health impacts (and costs) of burning natural gas indoors. Additionally, IRA subsidies partially cover the cost of stove replacement in the US. Upfront cost may be higher with induction today, but lifetime cost is lower due to the lower cost of electricity.

This frame also ignores the climate impacts, which I would argue have both significantly greater political and economic costs than not allowing gas infra in new buildings.

> What am I missing?

I agree that it is not viable to say “we must replace all gas infra today.” However, by allowing it to be built in new buildings, we’re locking ourselves into at least 15 years of additional CO2 production from this hardware at a time when we need to be reducing CO2 emissions as much as possible. CO2 not produced today is CO2 that we won’t have to draw down from the atmosphere in the future - something that also costs money. Not installing infra that produces CO2 is the easiest way to ensure we stop producing CO2

Beyond that - I’m not quite sure what your argument is. Is it just that 1% is too small to make a difference (or be regulated) - I’d ask you what is the cutoff at which it is viable for you? And what is the strategy for addressing emissions that don’t meet your cutoff?
