I think the thing that makes you easily replaceable is if you constantly are thinking incorrectly about something and are unwilling to be corrected by teammates because you aren't able to explain what you're doing and share your thought process. Writing buggy code and refusing to work with your team is a primo way to get canned. Owning the fact that there's time constraints and imperfect code and minimizing the risks taken and assumptions made by understanding the architecture is valuable.
Stand ups might not be the way to do it, but if even the prospect of sharing your thought process and explaining what you did strikes you as being 'micro managed', well.......
