My objection is mostly based on how much things annoy me, not necessarily on health.

Health-wise backyard campfires and BBQ are probably no better (or worse) than burning tobacco or pot.

Many places already restrict backyard campfires and similar. See eg https://www.theguardian.com/environment/2021/dec/17/wood-bur...

To expand a bit on my original comment:

So I might care about them doing a backyard campfire. If it's both legal and long-standing custom in that neighbourhood, I might just not move there in the first place. If it's illegal and I already live there when they start, I might object.
