I think it demonstrates that OP isn't in a team that has any autonomy or meets with anyone outside their team.

I've worked on a large, complex project for a large company, but the whole time I knew what the purpose of the project was, who would benefit from it, why the company was willing to spend money on it.

Even if you don't actually meet end customers, having someone who does put together proper user stories at least takes away some of the busy-work feel.

After all, it doesn't really matter how complex the tool is, what matters is why and how someone will benefit from it existing.
