You criticized people for "not lifting a finger" and get mad when someone asks which finger you personally lifted? You are only allowed to criticize people for living their life if you are not a hypocrite. It sounds like of the items you listed I'd describe 60% as barely lifting a finger (phone canvas, minimal value; "vocal" online, zero value) and 40% as definitely lifting a finger (volunteering at unspecified org) which makes you not a hypocrite by my personal math.
I personally have no intention at all of answering your question because I didn't make any statements as generally attacking as your own to start with, and feel no need to justify asking you to show your stripes.
I am not sure where guns came into play. However, I don't think you should be owning guns: you don't seem 100% stable given the disproportionate response, and I would worry that disproportionate response would come out while driving or other stressful activities.
Labor was free because of slavery, so the economics were not the same. Current engineering has the concept of "over engineering" which is what cracked-up addicts in wall street call "building to last", due to the "expense" of not being shortsighted on a quarter by quarter basis.
