" In your scenario, every person would be a profit-driven entrepreneur."
Again, that's only true in a profit driven society, I don't think you understood the main point of what I said in my original post.
First: from google: Profit = a financial gain, while Convenience = being able to proceed ... with little effort or difficulty. If one could lead to another as that is the discussion, but they are literally not the same.
So what is a profit driven society? If you live in US, then that's your society, a society in which you must profit or you will die (lose your job, go bankrupt, then you can't pay your bills, and eventually you go even homeless) then convenience will be used as a tool for profit, hence it will not bring anything beneficial and you are right as I said in the original post.
However if a society is not profit driven, i.e., profit is nice to have but not an essential part of it, meaning you don't need to profit to survive, then, it's the opposite, convenience will be a tool serving people to have a better life
