> Well, clothes are mostly down to weather and laws on public decency
Where I live, there are no laws against public nudity (as long as the nudity isn't "salacious" in nature). And yet, very nearly 100% of the people are clothed at all times.
And yet in other areas of the world, people wear no clothes.
People also smoke cigarettes, eat junk food, and do things that are unnatural and otherwise detrimental due to what they're bombarded with.
I wear clothes, I'm not a nudist. I have zero shame about my body though, it's a body—we've all got one.
The point as per my other comments: different solutions for different problems, the appropriateness of each varies with demographics. E.g., if you're surviving in an oppressive regime as a dissenter, email is something to be avoided. If you're running a business, it's likely fine, provided that it's compliant for your industry, e.g., HIPAA.
