Fire starting is a skill and an art. Anyone can use propane or butane. But having the skill to get a fire with the minimum material is a must have as far as I am concerned, and mowing the hard way will make it easier in adverse conditions even when you've got torches and such.
Having the skill to start a fire with minimal material would seem critical...but...
Having a means to start fire, be it a flint and steel, magnesium block, or lighter is simply wise preparation.
If that is all it is, basic preparation, a simple lighter makes a lot of sense, and there isn't much point in arguing over lighters versus other fire producing tools.
But what about being in a situation where
no fire starting tools are available?
If you don't know what sort of materials to seek out to create your own tools, you are pretty much done...
I need to learn more...

Waiting for "someday" will leave you on your deathbed wondering why you didn't just rearrange your priorities and enjoy the time you had, instead of waiting for a "better" time to come along...
