I know you like to poke fun at silly things. There is a reason that videos like Sheldon Brown's exist; they show technique. One of my bikes is a 29er, large frame. The saddle is roughly level with the bars, and that puts the saddle at about my belly button when I'm standing next to the bike. It's a big bike; I'm 6'-2". The saddle is positioned for proper leg extension to give me pain free power. I'm older and I have a very bad back, with 4 fused vertebrae, rods, bolts and a cage. I've been riding a long time and I ride a lot, I don't feel the need for a step through (yet) because I mount the bike properly, as shown, I lean the bike. I also dismount at stops. From the saddle my feet cannot touch the ground. This way I have the power to spin, without stress and damage to my knees and hips.
All that said, if and when I need a step through, I will get one. If I need a trike, I'd get one. I'll get a recumbent quad if it keeps me rolling down the trail and road. I don't care what it looks like, because when you're using it, looking down the trail, you can't see it. Just like stupid looking helmets, I can't see it when properly used. Most people just don't care what others are riding.
