this x100 - "IF you know what you're doing." when everything works and its areasonable success, it looks so easy - but getting all the different people talking to each other and building a product that a customer would pay to use is quite a challenge regardless of your product cost base (which anyways for the proper proudct market fit is a very small fraction compared to the revenues)
Unfortunately, I've seen many people spend outrageous sums and little or nothing for it.
Teach yourself how to code, know what you're getting into, get aligned with the right people.
But I think my biggest gripe with your comment is that it makes an excuse for not getting it done.
