Yeah, I'm with Nobby on this - 100% no ban. Perhaps part of it bias, given that when I was a kid a bunch of families would get together, pool their money and put on a mini-firework display in someone's back garden. The kids got to play with sparklers and squibs and everyone had basic firework safety drummed into them. There was something magical about that, and I don't want it to become one more thing that gets taken away and reserved for use by the authorities.
But in a wider sense, I loathe the tendency to ban everything enjoyable that's slightly dangerous, or that other people may find annoying. Every time something fun is banned or shut down it makes life in general a bit greyer, more boring and less free. I get that some people hate it, but I hate hearing dogs bark, drunks in the street or the next door neighbours having a party. That doesn't mean pets, outdoor drinking or loud parties should be banned (though there are people who would like to ban one or all of them).
