All analogies break down if considered from enough angles, but I think you're being overly focused on disruptive tech startups.
999 business out of every thousand are very similar to other businesses that have run before. Services, consulting, manufacturing, restaurants, shops, and even many types of IT companies, have built up a huge base of knowledge about what to do and what not to do, which is in the heads of those who have run this type of business already.
Even web startups are very similar to each other. Sure, some elements are unique to your startup, just like every road/vehicle configuration is different, but there are a lot of principle that apply across the board, and that a new entrepreneur is often completely unaware of. If that wasn't true, then approaches like Eric Ries' Lean Startup wouldn't be useful.
Thinking that your business is unique and different, that the rules that crush so many other businesses don't apply to you - that is precisely the disease that having a more experienced mentor can cure. Chances are, your business won't die from some unique combination of factors that was totally unpredictable. It will do something monumentally stupid and avoidable like running in stealth mode for 5 years (if you have the cash), building something nobody wants, or failing to build customer acquisition processes.
