Even if you could output $100k/month, you'd still be benchmarked against the next guy who could do the same. Maybe if you're capable of heroic acts, e.g. building an Airbnb quality app in 2-3 months, for highly competitive companies like Rocket Internet, or consulting companies.

The other option I see is doing your own thing, writing competitors for existing services. You'd probably need good understanding of products/users, as well as the ability to output several prototypes a day.
