Explaining the main chain is difficult enough, trying to get people to understand offchains too is a bit much.
I would bet that most people on this forum already use an "offchain" solution, in that they do not maintain their own full node. If you're using a website or an app to manage your funds, you won't notice the difference when your transactions aren't individually sent on the blockchain, but instead bundled up with all the other petty transactions and sent at the end of the day/week.
Are you appealing to your own emotions or instincts, or are you saying that most people use an offchain solution because it has not been proven that they aren't? You can't just pull such statements out of a hat.
