You're not being irrational. I did exactly when I cased some trails on a bmx. I had to then drive about 60 miles to the hospital (where my other half works) - the doctor said he wanted to leave it. Then I saw the x-rays (like yourself) and I pretty much insisted on an operation to put it right - for similar reasons, that I wanted the full strength back.
I don't think having a displaced fracture necessarily causes any weakness. When I did mine it was displaced by about 15mm and was left to heal naturally. I ended up with a lump similar to the photo above, but I've seen an x-ray of the site since and there's more bone at the fracture site now than there was before, so I doubt it's weaker.
I do however have some pain issues due to the now misaligned shoulder.
