I see this comment pretty much any time a well known artist points out art thieves.
Let me put it in perspective to show why it’s a rude thing to say in response to the situation:
Say someone has a nice house and someone broke in and stole things from them
It’d be like responding to their distress by saying “Wow I wish I was rich enough for people to steal from me.”
No.
You really don’t. And as ‘flattering’ as you think it might be, as much as you think you can ‘shrug’ it off and say ‘oh it just means I’m popular’, it’s still someone stealing something from you that you worked for and it still sucks. Especially when they start trying to sell it.
