Actually novel ideas are very rare and very valueable. That said you can build a perfectly viable business with not a single original thought. I.E. a restaurant or a clone of another business.

I'd split execution mainly in two: Building Selling

Building, barring some possibly extremely hard technical challenges, is not as hard as people make it to be, and LLM are definitely a huge help but I would never call vibecoding an entire application "Building a production ready SaaS".

Selling or, to put it better Product/Market fit, is what's actually very very hard and where most ideas fail.
