The challenge is allowing communities to grow. You have or want kids, which means that, without imparting a value judgment, you've contributed to some increase in the population. Likewise, your neighbors surely have had kids of their own, or they're planning to, which means that they're similarly contributing to population growth. All of this means that there will need to be more places to live. My question is: Where will your kids and your neighbors' kids live? As you advance in age, how does this play out when you'll want (or perhaps even need) them nearby to help? If/when your kids move away, will they be able to afford to move back? It's probably best that you don't have the answers to those right now, but they're worth thinking about in a climate where the law of supply matters more.
