>>1386078Sure, you can make a fire everywhere, it's both safe and legal.
Sure, you can make a fire during a SHTF situation
Sure, you can make a fire during a flood
Sure, I want to make a fire when I could just use a simply product that does it way more easily.
Also, while fire WILL kill bacteria, parasites and viruses, anything that lives, it will not filter big particles, heavy metals, and chemical products.
You can't boil brown mud water, drink it, and be certain that it'll be fine.
In some cases, a filter/purifier is better.
Both is the best, of course.
