I don't think you should have a ton of ultrasounds, or even "as often as you can," but there are a couple of conditions that warrant immediate care by trained natal specialists, and some that do mean c-section is safer. Yes, those conditions are rare! And yes, some of those conditions, like transverse presentation and placenta previa can be detected by a skilled midwife without an ultrasound. But I honestly do not think that all MW are created equal. I love my MW, but I find seeing and measuring the location of my placenta via u/s to be a fairly safe, non-invasive, and easy procedure that helps prevent major risks.
That being said, a good friend of mine birthed a baby with a heart defect that needed immediate open heart surgery. They actually went from birth, to airlifting the infant to a different hospital, to surgery within about 4 hours. That defect was NOT seen on her 19 week u/s. So u/s is not a sure fire screening for all issues. Like most medical tests, it is excellent at detecting the very rare, major issues, and okay at detecting the more common, subtle yet still serious health issues.
