As ad blocking increases, browser makers should add a type of &quot;in web-page&quot; payment system directly built into the browser.  Paywalls are annoying because of friction.  But imagine this instead:<p><pre><code>  1) open page
  2) short preview and button &quot;5 cents to read all&quot;
  3) click button and browser opens built-in dialog similar to how appstore&#x2F;play store in app purchase works.
  4) since its part of the browser, no concerns about trust or security.
</code></pre>
This kind of frictionless and cheap paywall has the potential to replace ads.  But browser makers must build it into the browser.
