Anti-static wristbands aren't recommended because it's common to fry electronics with static. They're recommended because in the rare cases where it does happen, buying replacement parts can be really expensive ($200-$500 for a CPU or GPU). They're like flood insurance. Floods are really rare, but can be really expensive when they happen. You are of course free to not buy the insurance, and 99% of the time you will be fine without it. But the 1% of the time the flood/static causes a lot of damage, you will really be wishing you'd spent the $5 on the insurance/wristband. So the fact that dozens of people post saying they were fine without the band is really not the point.
Also, static builds up more easily when the air is dry. This happens more frequently in desert environments, and in extremely cold climates (the moisture capacity of the air increases when you heat it, causing the relative humidity to drop). Most climates have sufficient humidity that static isn't a problem. But you are seriously playing with fire if you're assembling a computer in a low-humidity climate and you don't have a anti-static band.
