>I think this is what bothers me about these quippy, short-form discussions like we have on Reddit is you kinda always end up with "okay we all agree on X, right?"

This is a complete false premise word salad. I probably shoudn't even be engaging since you start up so disingenuously but ok, whatever. Just because I didn't write a multi paragraph rant in response to a deliberately nebulous example doesn't mean I'm being "quippy."

Nobody just arbitrarily decided "pre teens can't drive." Age limits were established for driving because the societal cost of bad immature drivers outweighed the negligible benefit of a few standout cases who are good enough to handle it. In fact, the trend has been to increase the age limit over time societal mobility has increased and tolerance for unsafe situations has generally decreased.

Developed, modern societies have all collectively come to roughly the same solution over literal centuries of development that there are things young people are generally not equipped to handle as well as adults and therefore should not be allowed to do due to risk to self and others. We don't let a 12 year old drive because the overwhelming majority of 12 year olds lack the risk assessment skills and appreciation for safety from a mix of lack of experience and biological development. We also set age limits for other things like drinking, other heavy machinery, pornography, and yes, holding certain offices. Likewise private companies like banks and car rentals won't extend certain business opportunities to people who they have similar concerns about because their investment risk is deemed to be too high.

Reasonable arguments can be had about any of those and whether the currently set limits are appropriate, but you're not the fucking arbiter of that conversation and you projecting about wanting to hear the "road of the crowd" or whatever is not fostering that conversation or adding anything of value. If the person who gave that example wants to expand on it and counter my answer to their question with some points of their own, they know where to find this thread. You on the other hand could no doubt find something better to do with your time that wax philosophical about what you think is the tragic downfall political discourse or whatever.
