It's mostly political. The conservatives argue no regulation of any kind is needed because the industry will self-regulate and capture all the leaking methane because it's lost money.

(Mysteriously, the methane continues to leak, and oil & gas continues to lobby against requirements to fix the leak)

As a secondary improvement, cheaper monitoring equipment might make the political fight easier to win.

Another improvement, the gas is owned by the public, and I don't believe royalties are paid at the pad but rather further down the line- after the leaks. O&G has little incentive to avoid wasting resources that "belong" to someone else that they have not paid a dime for. Just pump more.
