How comfortable is it to wear a u-lock holder this way?
tw: extreme anti-hipster /snark

Ahh! The u-lock belt holder. The perfect accessory for hipsters, literally:


Advantages:


Everyone will know you're a hipster
People may think you're into hardcore bondage
No ugly plastic u-lock holder marring the beautiful lines of your pristine lacquer-coated steel fixie
If you get mugged you have something to fight back with assuming you haven't parked and locked your bike
When you walk into a bar with your u-lock on your hip, all the other hipsters will admire your fashion sense and dedication to the art and science of hipsterism. They may even buy you a craft beer.


Disadvantages:


Everyone will know you're a hipster
People may think you're into hardcore bondage (thanks Mattnz)
Unless you're a bona fide bike messenger (who usually just carry their bikes into the delivery address rather than locking them up), you presumably don't have to wear your lock most of the day. So you have to keep your lock holder on you for the entire day, just for your 20 minute commute from Queens to Brooklyn
Everytime you change your trousers, you have to rethread your belt through it. Of course, real men never wash or change their jeans.
You are committed to wearing jeans or trousers with sturdy belt loop holes when you ride your bike. Then again, hipsters are allergic to lycra and would also never do a WNBR
if you fall while wearing it, it may hurt severely or actually cause you damage (thanks Criggie)
Hanging a 3 kg / 6 pound weight on your jeans is going to cause it to sag. But that's why you wear only the finest underwear.
Remember, too, that true hipsters do not tuck in their shirts -- so an empty holster would be hidden. So if you want that free craft beer from your fellow hipsters in admiration of your dedication to hipsterism, you need to carry two u-locks, one to lock your bike up outside the bar and other to carry on your hip properly holstered. Or you can go to the bar, sans bike.
