If you want to visit DisneyWorld, you'll need to buy a ticket and wait in line.
If you want to see the full moon, you can go outside and look up in the sky.
Often, we're tempted to create friction, barriers and turnstiles. We try to limit access, require a login, charge a fee... sometimes, that's because we want control, other times we believe we can accomplish more by collecting money. Clearly, people value the moments that they spend at Disney--with hundreds of dollars on the line and just a few hours to spend, there's an urgency and the feeling of an event occurring.
On the other hand, far more people look at the moon. Just about everyone, in fact.
If your goal is ubiquity, significant friction is probably not your finest tactic.
There used to be very few resources that were truly scalable at no cost, resources where we didn't need to use money or queues to limit who would use them. In the digital world, that number keeps skyrocketing. It doesn't cost a cent to allow more people to look at the moon, just as it's free for one more person to read this blog.
If you're going to add friction, if you're going to create urgency and scarcity, understand that it always comes at a cost. By all means, we need to figure out how to make a living from the work we do. But with scalable goods, particularly those that have substitutes, don't add friction unless there are enough benefits to make it worth our hassle.
