Which is why ideally both systems would exist. Some people prefer to read the same few publications all the time. Others (like myself) browse extensively and regularly come across paywalled articles. I'm clearly not going to shell out a monthly or yearly subscription to read a single article I find interesting, especially if this means spending thousands and thousands of dollars on hundreds of subscriptions to read all of the paywalled articles I run across. But if there was a button on top that said, "click here to pay .22 cents and gain access to this article", I'd be happy to do it. I could read a a dozen paywalled articles a day from across a range of publications and it would cost about as much as a cup of coffee.

Under the current system, we both lose out. I can't read the paywalled article and the publication doesn't get any of my money.
