The guy wants a PASSIVE INCOME ,
that means to earn money without investing or work.
This does not exist, except you have good luck and find cash in an evelope at an empty beach.
The very best what you can do, is to live in a nice but cheap developping country with low taxes,
but earn your money as a digital nomad at a level, close to wages at developped countries.
That makes it possible to save a lot, that you can invest and take off financially...but its work, not passive income.
Talking that passive income doesn´t exist is pretty easy, much hard is find a way how to achieve it.
You can have passive income for example when you rent your apartment or take dividends from stocks. But when you are talking about the business, it is semi-passive income, you need to manage it and improve it or it will die without your action.
