I raise pigs for pleasure and for a source of meat for my doings and I think it makes good sense to have them especially if you can purchase weaners and don't have to feed a boar or a brood pig all the time. I do this just because. Really doesn't make financial sense but I like to be completely self sufficient and not be relying on others for things.
There are worlds of things you can do with a pig. I'd suggest getting a large kettle and doing everything yourself if possible. There is a furtone in casings in each pig and cleaning one is pretty simple. I like to split mine and just cut whatever it is I want or how I want it. You can make hams out of the front shoulders too or even bacon. Endless opportunities with a pig. Very little waste too.
Patience please, I'm just trying to get on the learning curve.
