This is a big claim for you to make for sure :) . As someone who also lives in Texas, I'll just say that wanting space is not a problem in it self, but the argument of Texas has ~millions of acres of land and therefore wanting a few for yourself is not bad just does not hold when you consider the resourcing required to fulfill your want (tax money, water plumbing, electrical wiring, concrete and the alike).

If we take into consideration 'efficiency', resource-wise, when attempting to build a city that works for most, not just thee, it would end up looking like a high-density urban area that is in-fact walkable and small individual space for those in it.

This of course, does not preclude the existence of outskirts and places outside core density, which is was you want. By all means, you can have it, but degradation of shared infrastructure is to be expected. As in, maybe you have some unpaved roads, no water line or electrical etc.

This way the city saves on aforementioned resources, and yes including the good'old tax payer money. "Don't want my tax payer money subsidizing your choices" is common phrase used in this state. By that logic, "I don't want my tax payer money subsidizing your choice to live outside the would-be dense city" would apply here.

Sadly, this state does rely in ever-more sprawling city design that will bring about its financial demise as the cost of maintenance and upkeep catch up to a slow down in the state/city tax revenue. Checkout urban3's work on city financials https://www.urbanthree.com/case-study/
