I’d argue being an Olympian, which requires relying on a mix of public funding, ones own resources (usually family or sponsors), and gives an international platform, media coverage and potential prominence is a privilege given quid pro quo for behavior befitting that privilege.
Post-rehabilitation and having served one’s time - There’s no reason this person couldn’t practice their sport in private, there’s no reason this person couldn’t be a private citizen with a regular office job.
However, I’m sure you could agree that they shouldn’t ever be allowed to work with children again, so there must be a line of compromise you agree with.
I’d also argue that knowing that one’s mistakes - although paid for - may have lifetime consequences - are also part of the rehab process. Like how alcoholics can never have one drink again.
