Yeah, I'm not saying it doesn't make sense or that the EU wouldn't do it. I'm saying they aren't doing it, because the treatment is of unclear efficacy.
I thought it sounded like quite the opposite: he's not saying they aren't buying it because they're cheap (he points out that if it worked, and they were trying to be cheap, they would buy it). He's saying they're not buying it because it might not work very well.
