Hi Levi,
The problem is that there is almost never a moment where there'll be no activity on your computer. For an example, spotlight indexing, time machine backing up, and so on are being done in the background without you noticing them. A finder browser window is an access and an activity to your folder, it has to refresh to make sure you're not viewing an outdated list. If it wasn't doing that, you'd have no idea if a file was moved, deleted or updated elsewhere.
The encryption process is sensitive to any changes and even a slight bit of data can interrupt the entire data stream, so forcing the encryption to stop in the middle of the stream can be very dangerous and harm the data integrity.
However, we can understand why the auto-lock feature would be useful and we'll look into it.
