I had to rope a filly last year...she would not be caught, period. I could round pen her til she was dripping wet, she would come up, allow me to rub her all over, but as soon as I had a rope or halter near her, she would take off again; and she wasn't nice about it...she would give me both barrels every single time...so it was dangerous as well as frustrating. I finally got tired of that, and decided to get a rope on her, and let her figure it out for herself that she wasn't going to get away so easily every time. Sure she faught it, but she didn't hurt herself, nor did she get dropped to the ground...the only thing she was "forced" to do was face up to me, and allow me to pet her, and rub her with the lead, and halter; I would then send her to the end of the line and 'round pen' her some more. After getting her to face up and allow me to rub her all over with my tools I took the rope off, and went back to normal round penning, and the change in her behavior about being 'caught' was much better...she would allow me to rub her with the tools, and eventually I haltered her several times without her darting off in the other direction and kicking her heels at me. That was the only time I ever had to 'rope' her...she had been so used to giving everyone "the finger" over being caught, but I guess I gave it back to her by roping her and making her figure out what I wanted.
Now is this a technique I prefer to use? No, not at all...I prefer getting a horse to work, and letting him figure out what I want without roping and 'forcing' him to hitch up to me. But when it's taking hours, and days for the horse to "get it"? That could mean a horse gets injured, and you have no way to treat him because you can't catch him.
