Yea, I agree. Cows also live about 20 years, so even not breeding cows wouldn't solve this problem. The morality of eating butter is kind of a moot point when all the production mechanisms are already in place and they aren't flexible.
A possible solution would be methane fixing bacteria (methanotrophs) in the guts of cows or in the ocean where
> 75% of the current concentration atmospheric methane originates. The ocean also contains a significant amount in solid form that gets released as temps rise. [0]
