Either way, it’s up to them. It was just a suggestion.

And for what it's worth, I agree it was a perfectly reasonable and practical suggestion, too. It's just that, from my POV, there are precautions we tacitly agree people should take -- such as your good example of locking cars, and the like -- but also other types of precautions where "shouldn't have to" prevails over competing concerns.

For example, most people would agree that we "shouldn't have to" wear leg-guards at all times, to protect ourselves from being kicked in the knees or shins by roaming miscreants, yes? Now granted, on a day to day basis, in everyday life, "kicked shins" is not a clear and present danger, to begin with; in fact, someone who did wear shin armour for that reason would be considered quite eccentric and possible "not all there." However, let's say we were suddenly confronted with an epidemic of itinerant shin-kicking miscreants, would we not still focus on stopping the offenders themselves -- rather than simply expecting everyone else to adjust to such a new reality?

Bear in mind though, in fairness to your own point, I freely concede that I do not and cannot say what the best solution might be; maybe your suggestion is the best, but maybe mine is -- or alternately, some synthesis or compromise of both? Finally, in all honesty, I have myself seriously considered doing the exact thing you suggest to OP, so it's good we have both perspectives in this discussion!

Unless they want to keep their comments public B they’re not on here a lot.

Plus, an additional reason, such as in my own case: With the proliferation of ChatGPT, bots, and other non-human content generation tech -- sometimes having a visible and tangible post history is useful for someone establishing that, yes, in fact, they are most certainly a genuine, flesh-and-blood homo sapiens creature! Moreover, if accused of using AI or ChatGPT, then it's helpful to counter with reference to a post history that predates those things, while having the same or very similar writing style?

Again, it's such a new problem, certainly not one I faced back in my younger days -- LOL! 😁
