——Sorry, there is about 688,800,000 1/4 acres in Texas, so we would need to use a couple of more states.——
You could fit more than one person in each house that fits on 1/4 acre. Maybe 5 or 6 people per house?
That would leave the rest of the earth void of human beings.
The real problem in the developed world is population decline.
Current world population is estimated at 7.014 billion. If existing trends, decline in industrial countries balanced against rise in agrarian countries, are maintained it is estimated that population will peak around 2080 with just over nine billion. So we will probably need to expand into Oklahoma as well.
