IMO if you can become a $100M household name without VC, that's absolutely the way to do it.
Even if you do take the VC path, YC for me was a massive boost in network, knowledge, and resources that I didn't have before, but it's also not the only way to acquire those things. You can even find that YC knowledge online, e.g. https://www.startupschool.org/.
That said, if anyone's even considering applying to YC, I'd recommend it, at a minimum it's a forcing function to think more deeply about your idea or business when assembling the application.
