I'm quite sure we all started somewhere whether it was kits be it liquid,DME or all grain regardless which gives us all an insight different or not as to brewing beer Some have the confidence/experience to move on though others find convenience to stay put.
You can brew beer with what you have in the kitchen cupboards but once you step up you have to upgrade your equipment,time and knowledge and some do and some don't but again this is down to the individual to decide what they want to do and sometimes it's cheaper to buy a large bag of grain but not convenient.
