This would be a solution if the problem was social media. The problem here is the intrusiveness of advertisement. Personally targeted advertisement exists on the non-social web, on the phone, in your mailbox, at your door. Group-targeted[#] and still intrusive advertisement exists in the public transports, on the radio, in newspapers, in the streets, on most "things" in your house (as branding), on your clothes. I think by now it's clear that we cannot realistically avoid substantial amounts of ads by simply changing our personal behavior. Just like for ecology, it is a common mistake to depoliticize the problem by advocating only individual actions. Defending oneself against ads has to be done in whatever community you are part of using the available power levers (that were put there exactly for that purpose). This can be the state level but also as a union, in a neighborhood. Advertisement should to be (more) socially controlled and regulated.
Advertisement is inherently intrusive, it's goal is to make you listen to some message you didn't ask for. It is strictly one-way communication and as such it's deeply authoritarian: tptb have the right to talk, you are coerced to listen (it goes against fair access to public speech, which goes against the ability to exercise your power on society as a citizen). It is based on ethically questionable methods: psychological manipulation and information gathering; to provide some hindsight, when performed by an individual and not a corporation, we call this behavior harassment or psychological abuse. Yeah sure, you might be stalked by a nice guy with whom you could be friend just like you might see an ad on an interesting product, but no, stalking is oppressive even if done by a nice guy and harassment is a tiny fraction of the possibilities you have to communicate. You want to get a new fridge? Ads will not help you while an independent comparison or buyers guide will. You cycle a lot and would like to keep up-to-date with related products?

F ALL ADS
note: i didn't properly define "ads" here but broadening from pure "commercials" we could have mostly the same arguments against all sorts of "public relations" like corporate communication or modern vote-based politics.
[#] there is no such thing as "non-targeted advertisement"
