I am curious which of the following (if any) you would define as alone:

1) one person but they take VC funding

2) one person but they use open source solutions

3) one person but they live with their parents

4) one person that lives completely off of what they earned themselves previously, but they did get government funded student loans that let them make money in the first place.

Don't forget:

5) One person with a copper mine and a soldering gun.

None of these. Even the guy who runs the Primitive Technology youtube channel, building up technology solo from literal sticks and rocks he gathers himself, would not be alone, because he did not too personally manufacture the digital camera he uses to record himself creating these things.

Also, was he not born? Can anyone be said to do anything alone, who did not themselves arise spontaneously from the primordial soup?
