I think the same resolution problems arise when you are using a very tiny mirror. It may be that lasers have it easier since their light is coherent. I would have to do some research into these issues if you want more detail.

That's the problem with these extrapolations. We quickly spin off into a neverland of inconceivably advanced technology. If there are mite-bots crawling into the brain, probably there are immune-system bots to fight them off. It's not obvious which side will win. Until we know, the jury is still out about how much privacy will be possible in the future.
