My aunt had bunion surgery when she was in her 50's. They also shortened her big toe during the surgery. The surgery went well. She only had one foot done because the bunion on the other foot wasn't causing her pain. She lived into her 80's. If she had arthritis, it was minor.
I don't remember that she had to use crutches for 2 months. If you would have to use crutches for that long, doing it now would be impossible, I agree. I'd first try to find a way to make your feet more comfortable.
I suggest that you go to a shoe store that provides orthopedic shoes and appliances and ask what they can do to help you protect your bunion joints so that you have less pain. My aunt had and I have a genital condition called Morton's toe, in which the second metatarsal bone is longer. This results in the joint being out of line with the rest of the joints. My parents took me to a podiatrist when I was young. I learned early what I needed to do to prevent bunions.
Perhaps if you try some of these things you can reduce your pain. Be sure the toe box of your shoe is wide enough so that your toes can lie flat and not be forced to point towards the center. Wear low heeled shoes. I have to wear a shoe with some heel, no more than an inch high for everyday, because my foot needs some arch support. While in my youth, I wore a custom fitted arch support. But I was able to strengthen my arch muscles enough, with exercise, that I now have a natural arch. For bunion, I think you'll need to wear a supportive shoe most of the time to keep your arch supported. The podiatrist and/or the specialty shoe store may be able to give you more info.
They will definitely be able to fit you with shoes that will provide you with more comfort than other shoes. You may have to try out different shoes, wearing them for 30 minutes or so, in the show room.
My mother had bunions because she went barefoot or wore flip flops for much of her life. She never felt that she had enough pain to have surgery. Once she had the bunions she began wearing low heeled shoes with boxy toes. She also had some relief with putting foam cushions between her big toe and the second one. The end of her big toe rested where most people's third toe points. She walked until close to the end of her life at 86.
Here is a web site that might be helpful. http://www.footankle.com/bunions.htm
Here is a site that describes various types of surgery. One example said that the woman only had to be off her feet for a couple of weeks. How long you're off your feet depends on your bunion and the type of surgery used.

There are several more sites that I didn't look at.
