> ArXiv won't let authors remove their paper from the website

This is an essential feature of arXiv to maintain academic integrity and encourage serious academic submissions.

If you realize that your paper contains an error, then you can mark the paper was "withdrawn". People have limited time so if you do this no one read the paper (everyone makes mistakes sometimes).

As long as you do not make a habit of uploading and withdrawing papers, then it will not matter.
