If your injury is minor and you're uninsured, you're going to be dumping potentially thousands of dollars just to receive some gauze and time, or an IV and being ignored for a couple hours. It's seriously unimaginable for most Americans to even consider an ER visit for something that's not life threatening or extremely severe.

$300 is unimaginably cheap for any level of care. $100 is less than the cost of a 20 minute scheduled visit to an in-network doctor (before/without insurance, which tends to bring it down to about 10-30 dollars). It's so absurdly cheap that, while I get the spirit of suggesting it's not free, that's absolute, absurdly low-cost compared to America.
