Passive in terms of time commitment and effort. I don't think there are truly passive income streams unless you have substantial capital to invest in the first place (eg: vanguards and rental property)
I think scalable income is a more useful concept than passive income. What I mean by scalable income is when you can increase your income by investing more capital, but keeping time commitment and effort at the same level. In my view purely passive income is either some instance of rent-seeking, or simple risk-free return on economic growth. But even those require a minimal level of effort.
