That soundbite also over generalizes touching as being only sexual. Touching can be an effective way to show compassion, empathy etc. We lose out on that opportunity during Nedah.
I disagree. I think needing to be able to work things out without the compassion etc. element of touch is also important.
To quote a nurse at the maternity ward, speaking about frum men interacting with their wives in labor:
"You are able to do with your eyes what most people need to use their hands for."
