<i>If billboard advertisers had to pay every person whose life experience is degraded by seeing a billboard for a product they&#x27;d never buy</i><p>I&#x27;ve never found my life &quot;degraded&quot; by a billboard, even if it was for a product I&#x27;d never buy.  In fact, some of them are still useful, especially when driving long distances on the Interstate.  They&#x27;re something to break the monotony and give you something to think about, if only for a minute or two. Some are downright funny&#x2F;amusing, and others at least provoke a &quot;I wonder what that&#x27;s supposed to mean&quot; reaction.<p>&quot;cognitive pollution&quot;?  That smells suspiciously like bullshit to me.
