This is about what it sounds like. Some Denver radicals are trying to ban a particular kind of business within Denver. Frankly, Denver voters are so far left these days that I think they might go along with this despite the various harms, including job loss, it will cause. And by the way, did you even know there was a lamb processing facility in Denver? I'm sure you didn't. Which emphasizes how utterly unnecessary this is. It's more of the same kind of radical junk from the kinds of people who brought you wolf reintroduction.
