Its an utter fallacy to state that you have to stop doing quality processes if you want to deliver software, rapidly.
Abandoning quality review steps only seems to be 'more efficient' if you're utterly crap at doing quality processes in the first place - but, the more you do them, the better you get at it, faster - so really you're just saying "people who are crap at doing quality-control processes on their software don't want to have to get better at doing quality-control processes, because it just slows them down" .. effectively ignoring the time wasted in bug triage and other user-unfriendly experiences that result from this lack of quality process, down the line...
So I don't buy your argument. I think you might just be crap at software quality processes and don't want to be reminded of it. Maybe you make donuts - some of us actually serve healthy software to our users.
And many of us do it just as quickly as the guy throwing pieces away that he doesn't know how to use, effectively. Albeit, with much higher quality results, naturally.

The problem is you circled back to valuing user experience itself, while MONEY(UX) looks like a sigmoid, not linear. As long as the UX isn't so horribly broken that most of your customers walk away, it's stupid to spend resources improving UX because you'll get marginal gains at best.
The largest airline in EU is Ryanair. You book it because it's the cheapest. The flight is delayed so you're late for the train, the seats are uncomfortable, customer support doesn't exist, you get constantly bombarded with ads, your day is ruined. You hate it but what are you doing to do next time you fly? Book Ryanair because it's the cheapest. You know it, they know it, your mom knows it.
