You don't have opportunity cost of missed business, if the alternative is that you don't exist. If it allows you to launch faster, you aren't losing business by not having every feature; you're gaining business that you would've lost by not launching sooner. You can always build the extra features later.

Midjourney avoided having to make a frontend at first, meaning they launched faster. Once they got product/market fit, they built a web frontend, which is now better than the Discord interface. Seems like a pretty smart strategy, that worked well, for a completely bootstrapped company that never raised VC.
