A lot of us wage slaves live in areas that are too spread out to bike, have no public transportation, and we can’t afford to move to a higher COL area that has those amenities. For example, my commute to work is typically 70ish miles, one way. There aren’t better job prospects within my niche industry that are available to me. I’m working towards moving closer to work, but I’ll be moving to a smaller town that is even less bike-able/walk-able. IMO, your position requires an amount of privilege I don’t have.
As an American, the craziest thing about that story is that Australia changed their gun laws after that happened. Imagine a government taking reasonable action to save lives… Wild.
