Actually, bacterial silver resistance exists. Typing those words into google gives a long list of abstracts and similar. The top one is titled: "Bacterial silver resistance: molecular biology and uses and misuses of silver compounds."
The thing about resistance is that it may come with a cost. When that is significant, resistant bacteria will be broadly restricted to places where the toxin is likely to be encountered.
This isn't quite as encouraging as you might think, though, because the little buggers can pass resistance around, and some resistance is likely to remain somewhere in the population. This means even if you stop using the antibiotic (or antiseptic) for a few years, if you start using it again the resistance get back up to high levels quite quickly.
