Exactly this. If I woke up with a million-$ idea tomorrow, chances are good I could not just get up and just pursue it. Why not let someone else take the chance?
Add to this that, as time progresses, more and more ideas that are doable by a person (or a small group) are already done. So your idea needs to solve its problem better (by whatever metric, e.g. price/usability/...).
This is somewhat countered by improved tooling (e.g. stripe, node.js, $stack_of_the_week) and cheaper tech (e.g. raw compute power), as well as by growing and better interconnected global markets (the global equivalent to opening a specialty shop in a tiny village or a booming mega city).
