I consider that a feature. Working and training problem solving skills and persistence through trial-and-error to the degree required for that kind of thing is great. I feel it's underappreciated in potential that treating a wide swath of these kinds of rules as nothing more than cattle-fences can have a shockingly positive effect.

One of the biggest problems that grows with each generation, is how do you get the youth to actually engage in constructive development of real skills? How do you get them to be interested in something that will be useful for society down the line? Quietly looking the other way while a statistical minority breaks some of the safety-rails of society basically solves that problem. Breaking the rules is cool. You're basically exploiting the rebellious nature of the youth to trick them into learning useful skillsets. So long as the hurdles to circumvent the rules remain reasonably involved to overcome, and the secret intention remains unspoken, you basically double up the rewards of the rules.

I was going to say that it's a great way to teach teenagers how to modify and compile a browser.

Or just uses any of a gazillion proxies that strips the "I"m under 18" bit.
