Where we are talking about areas that are already almost entirely paved with sidewalks and minimal trees or yards, etc., then we agree — there's no environment to preserve — it is just the character of the human-only habitat. converting this from single-family postage stamp lots to high-rise apartments is in most cases a reasonable tradeoff.
But NO, you obviously do not understand, let alone have any sympathy for, preserving environment and habitat. It is not merely inconvenient, what you propose is death for everything from the insects, birds, flora, fauna, and 50-year-old endangered turtle living in the wetland behind my neighborhood. Paving paradise and putting up a parking lot is not a solution.
Beyond that, you are proposing to literally steal uncounted millions of dollars of built-up value. Everyone in this area has willingly paid large amounts of extra costs and far higher taxes to maintain its character, purchase lands for greenspace preservation, trails, etc. It is not mere inconvenience you are talking about, it is literally stealing all of that extra value, and handing it to the developers who will strip the land and put up (almost universally shitty quality) buildings and pavement. You need to compensate the residents who will be displaced, not merely hand their value over to the developers, destroy the habitat and "inconvenience" the current residents.
Moreover, even if grocery and convenience stores "popup" with demand, they will still require cars to get to for almost everyone. It also fails solve the problem of where will be the JOBS or any other supplies. Most things will still be a significant drive away, and you've just solved one problem (lower housing cost) to add another — the requirement to spend money on multiple automobiles per family. And the added pollution and resource usage.
Your problem is you think there is a single simple solution that applies everywhere. You are wrong.
In some cases, it is a great solution. In others, you are literally destroying everything to gain nothing, because you can't be bothered to think about it more deeply. Any society doing that is doomed to failure.
