"Covering up" has not much to do with practicality unless it is to block excessive sun or cold temperatures.
If you are a soldier or warrior of some kind, or even just an adventurer à la Lara Croft, covering up has much to do with practicality. Keeping the sun out or the warmth in are just one aspect. You typically have to engage in many physical activities that involve your body moving over rough, edgy, sharp or whatever surfaces, where you would very much want to have a layer of protection between your skin and said surfaces. Just try crawling through thorny undergrowth or slide down a pile of dirt and you will realize that. Clothing also provides some protection against all that stuff flying around on battlegrounds, dirt, rocks, debris, whatever. Not bullets or grenade shrapnels, obviously, but plenty of the other stuff.
And all that is still without adding any type or armor. Which is often part of the picture, in the virtual worlds in consideration, aggravating the not-covering-up-the-most-vital-body-parts issue.
And yea I'd consider practically nude men, like the one in your picture, as sexualized depiction just as much. I'm not sure how you can look at a movie like 300 (which may have inspired this picture) and say, yea, nothing sexualized about that, no gay aesthetic or eye candy for the female audience at all.
