As someone who has just started the journey towards coffee snobbery, I quickly had the impression that the grinder is the most important piece of kit needed, but from my research the electric burr grinders <300$ were hot garbage that produce very uneven coffee grounds, resulting in a very hard to control brew. But this is just YouTube and Reddit knowledge, would you agree? I currently have my eyes on a Niche Zero grinder, but at 560€ it's quite the investment. If you then buy a Chemex, V60, Aeropress or any other brewing method is a question of choice, but don't forget to filter your water before using it...

My point is that this effort is not feasible for most people. If my morning drink takes me more effort than getting showered and dressed, i'll probably forgo it 90% of the time. I'm working on this form of laziness, but that's the willpower/patience most people have to live with. In addition there is a whole host of other reasons why something that's easy and routine for you can be quite vexing for other people.

Opening a can takes less then ten seconds, we're already talking about a harsh diet change, we don't have to make it harder than necessary for people.
