2. The alternative is letting people get AIDs. This is more expensive than PrEP.
3. Insurance doesn't pay the full list price of drugs, they pay a lower, negotiated rate. CostPlus Drug Company charges about $20/month for PrEP. This is probably closer to what insurance companies actually pay.
Other methods of protection fail. People lie about the status. People don't know their status.

I know it's not popular, but AIDS is just what we have now. If people continue living like this, there will be another, and it might be worse. Hell, we probably already dodged a bullet with Monkeypox due to concomitant COVID precautions.
Hell, in the UK heterosexual cases of AIDs overtook homosexual cases because of adherence to medication and good practice. [1]
