It seems idiotic to intentionally not bring an ultra-basic item that weighs +\- nothing, all because you are worried about a hypothetical on top of a hypothetical, ie one out of a million times you have a true emergncy, and of those emergencies one out of a million times you let your emergency fire get out of control.
The cost of not having the fire when needed is high, the cost of bringing a lighter is ultra-low. You can still choose not to use it, but if you actually need it you’ll have it. Its not like you will be careless with it, either—that regulation is to guard against idiots, not because its impossible to utilize a flame without accidentally starting an out of control fire…in this case the conditions that justify the ban (super dry) also more or less preclude needing the fire in the first place (ie only needed if wet). Even if that sudden storm and cold front doesnt bring the area out of a drought, it’ll still be wet and not “tinderbox” conditions, and theres a good chance you can stay with the fire and not let it spread. Just dont be an idiot and all will be fine. It takes so many stars aligning in exactly the wrong way, all at the same time, for this to be approaching one iota of an issue, that it surprises me it’s even a topic. Zero-% chance I choose to be unprepared based on a temporary regulation like this.
