>Targeted ads, even imperfectly-targeted ones, are "less wasted" than other kinds of ads.

How do you know that your 'targeting' is working? If you target females how do you measure how many females saw the ad? Targeted ads should go to the targeted audience or they likely went to waste - at least the advertiser didn't get what they paid for. The quality of your targeted audiences matters to your advertising customers.

You get better conversion, in aggregate.

Even if that is true it comes at the expense of a lower signal to noise ratio - you are adding noise.
