It's too late. You can't start to charge for things you used to give away for free. Plus with the internet, there's always an alternative, you just haven't found it yet. So the moment you run into a paywall you will turn around and start searching for the same thing you were just looking for but for free.

Because the existing paywalls are some nonsense where you have to give them your home address and sign up to pay a recurring monthly fee which you know is going to be a bear to cancel and costs dollars rather than cents, whereas what it ought to be is a browser plugin that just pays them automatically when you visit the site as long as the amount is below your threshold (with a circuit breaker that requires you to manually approve if you get charged more than like $5 over the course of an hour).
People have been talking about this idea for maybe 20 years (that I can recall). I'm also pretty sure there've been numerous attempts at implementations because really it's not that complicated a thing to make.
None of them caught on though because when it comes down to it, most sites that successfully make money can probably make more money from advertising than they can from this microtransaction system so there's no incentive for them to adopt it.
None of them caught on because the regulatory environment makes it effectively impossible to implement efficiently and all of the attempts had to make fatal compromises in order to comply which made them useless.
