Accessors are hardly a pre-generalization. I believe he was simply telling various use-cases that can be applied. Yes, software requirements change and some things don't (in practice), but you won't know precisely what will and won't need them until you ship. And even then, you may not know what will be required years from now. It seems like the rational option is to sink a second or two more time into the development in order to save potentially long and annoying refactors later. I've been using Visual Assist and I can actually get it to dump an accessor into the console faster than I can type out the full variable name (for variables name that aren't i,j,k).
On a more serious note, trivial accessors generally don't result in any more compiled code than direct field accesses, but do have the advantage of abstraction. If your development process is limited by the time it takes you type out the name of an accessor (or in my case, the first 3 letters), then you must be really productive or not do other things like documentation or testing.
