I don't see how that would be "better" or "easier". It might very well be "cheaper" indeed but I'm a vaping consumer as opposed to a vaping hobbyist. I'm enthusiastic about vaping as a way out of smoking but don't necessarily see it as a learning goal in life or a new way to focus my gadget spending on, sorry!
I think his point was by the time you fill a pan with water, get it to boil, wait 10 minutes, wait another 5 or 10 to cool, and finally wait for the cotton to dry out...one could build a coil and have been vaping.
As for a life goal, you've put more effort into trying to clean a coil (figuring out a method) than many do building or just buying a $2 coil. You were just being offered a piece of advice about simplicity of rewicking, if you were to build.
Now for better or easier, that's personal preference we each have to judge. I can say it is easier and better for me to use a dripper with coils I built because they last longer and I feel I get better flavor. My coils can last up to 3 months and wicks can last up to 2 to 3 weeks before changing.
That's my choice though and not for everyone. You're not into building, nothing wrong with that at all. However, just because someone says something contrary to your view doesn't make them wrong or off topic, as it still pertains to coil changing. A simple response of you don't want to build would have sufficed, there was no call to attack someone.
I personally would say boiling could be a bad idea. Boiling could cause bacteria to grow in a coil, if it isn't properly boiled and dried or stored improperly. I also have had times when I tried it, that it brought off flavors afterwards and was just much more simple to buy a new coil and be done with it.
That's my personal view though, doesn't mean I'm right and you're wrong. Just means we see things differently.
