I think the problem is that we don't have a great way of quantifying the impact, so the tradeoff always ends up being something like "people are literally going to die, is pleasant light worth human lives?" The answer IMO is "yes, if the number of deaths is small enough relative to the total amount of pleasure that the pretty lights create", but without a quantitative framework it's pretty tough to make that call.
