Short employments and gaps are a signal. Not a great one, but easy to identify. If you've job-hopped before, you probably will do it again => prefer someone who doesn't have gaps.
It's perfectly fine to have gaps and "live a little" or even a lot, but it's also perfectly fine to prefer people who you believe will provide more value to your company.
I think you're conflating short stints/job hopping and resume gaps. How does a "temporary period of non-employment" preclude someone from "providing more value to your company"?
There are infinite reasons why someone might take time off. Its arguably far more responsible to do so than continue employment and lower the priority of employment obligations in your life while you tend to other aspects.
