I think those are two separate ideas. I agree we shouldn't have a culture of "farming out" childrearing, but I disagree offering childcare options has to encourage that. I think in any case, we need work environments more sensitive to work/life balance.
A lot of parents who chose to stay at home described having multiple young kids as chaos and "just trying to survive." I also get, "It's just so nice to talk to adults." Higher end communities offer a lot of options for temporary childcare; daycare programs that are 2-3 hours, gyms, and groceries offering childcare while you're there that seem specifically focused on stay at home parents. Those aren't options for most people.
Just an hour or two break can really help recharge, or just plan appointments or outings. If you're lucky enough that they sleep through the night or nap, you're still tethered to the house. I really think doing things outside of a relationship helps make parenting more fruitful, but since being a parent is 24/7 you just don't have options unless you have a strong network and are willing to ask/pay for help.
