I have to agree with this. Doing an oil change once or twice a year and not using gloves isn't going to hurt you. Believe it or not it is possible to do an oil change without getting the mess all over your hands.
There are products, such as this below that can be used to coat your hands with before doing the work.
I've found that just using some hand cream before starting work can help. It helps seal your skin a bit and prevent stuff from soaking into your skin.
YMMV
A few months ago, I might have agreed with you.
I grew up when you worked on cars with your bare hands and used good ole dino oil. However it was natural & thick, etc. & your skin is a protective layer against most contaminants.
However we have not changed. Although college educated, it appears I have used new synthetics without proper hand protection.
The more research I do, the synthetic oils are designed to catch microscopic particles. Not only that, they are designed with all kind of micro and nano particles additives put into the oil.
There even a picture of a scientitist with a tiny microspe slide of motor oil that has nano infused chemicals in it..he has gloves on while holding the slide by the very tip almost as if he's afraid it will get through his gloves.
You can bet for sure if diseases like hepatitis, hiv and ebola can penetrate the skin barrier via blood. That nano and micro particles from used synthetic oil damn sure can. Even new synthetic oil with all it's nano additives has to get through your skin.
Sure potassium and salt and iron are in our bodies already but
Chromium, boron, lead.. those are nano/micro particles we can do without.
All these nano and micro particles yet no warnings on the synthetic oil labels.
It just amazes me how I never gave this a second though before.
To each their own, but for me it will be gloves from now on.
