This is such a common argument for everything NIMBY. Your point remains valid, but the argument you've presented comes across uninspired.

What if you had no way to stop or from happening; what do you think might be reasonable mitigation steps that regulators could take to minimize the risk to your BBQ?

If something becomes an inevitability, you probably should be prepared with an argument that is accepting of that inevitability while still addressing your worries/concerns.
