Too expensive. Google makes, on average, smtg like $50/user/year or something (not an accurate number). Now obviously this varies, so some people are much more valuable, and some are less valuable. The value depends on many things, but one of the biggest factor is purchasing power.
Now -- if you're willing and able to pay eg. $10/month for Google Premium, then you likely worth much more than the average user. So the more you're willing to pay the more you worth as an advertisement target. I am not sure where those curves meet, but I presume it'd be a lot.
