Doesn't seem circular to me, they are against current zoning because it goes beyond what they consider "egregious". Lighter zoning that only dictated limits for sound levels and chemicals used would probably fit their definition of good zoning.
As an example, I was going to buy land in a rural town to develop into a nice little mini tiny home resort. It was going to be super cute. However, the zoning meant I couldn't do it. Not because there wasn't something just like it next door (like other resorts). No, just beacuse the letter next to the property in the registry wasn't the right one, and changing it would be a nightmare. Why? As long as I'm not dumping heavy metals onto neighbor's property, the water, or the air, why do these letters hold so much sway? Exactly why do we need 'recreational-only' property right next to an existing vacation business? It only serves to entrench existing competition, and make new ventures more difficult.
Satisfying their definition is not an obligation.
