If I buy a book, I'm not required to read any part of it. I'm allowed to control what I read.

You might be safe as long as the ad is on a website but stupid laws that shouldn't exist like the DMCA can make it illegal to block ads when you have to circumvent a technological measure in order to block those ads. Blocking ads and the steps needed to block them might also violate some product's EULA which could result in civil judgements against you.
