If you'd rather have less time to yourself, then that's a perfectly acceptable choice. As an introvert myself, I'd rather have more people to share household and child-care activities with, because that would increase the amount of time I have for other pursuits. I don't have kids myself, but I know people who do and the amount of time they spend dealing with them is incredible. I do have a house though, and even there the amount of time I spend on upkeep, repairs, cleaning, and cooking is significant. Having roommates I have little emotional connection to has pluses and minuses: you can share some of the expenses and household duties (if they're good roommates), but the minus of having less privacy kinda sucks. But if you're closer friends than that, it's not such a problem and is actually a benefit by having more emotional support nearby. Also, with more incomes you can afford a bigger house (since house size does not scale linearly with bedrooms; bathrooms and kitchens are the most expensive rooms by far), and this gives you more space than you can afford on your own.
