The problem with buying cashflow through ETF investment is you have to make so much money to get to any real level of cashflow.
Buying $30k of index funds will set you back ~$50k pre tax, which is 25% of our doctors income. If you subscribe to the 4% rule, you've "bought" a perpetual cashflow of $1200 annually.
To get a passive income of $200k annually, you need $5m in index funds which is going to take either ~30 years with compounding interest at 10% (assuming you are investing a continuous $30k after tax) every year.
Realistically, to make any sort of actual money (I'm defining this as $200k + annually in passive/semi-passive income), you need an ownership stake in a business or in another asset (likely property).
The vending machine example is stupid for a doctor to do, because it's the sort of opportunity that rewards someone with a lot of hustle and low opportunity cost - good luck competing with an entrepreneurial college student who has a lot more free time. Same thing with the website.
