What do you say we try it and find out?
> 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).
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.
