Of course, but we're not talking about people in poverty, or that are homeless, etc. You're just bringing up a weird red herring that's orthogonal to my point--namely, that the bar is extremely accessible (esp. compared to ventures prior to the advent of computers).
More people than just those below the poverty line work on weekends. Launching an app over a weekend is easy...if you've got all of the required skills a priori and the leisure time available to do so. Launching an app over the weekend isn't a viable option for people lacking either of those two components no matter their distance from the poverty line.
