No i dont think so, however this is only because Iran internet and if we were talking about having to not relay on Iran internet companys you wouldn't be restricted to such limits. The internet is blocked for Iran but you can still use computers and so you could sell software or games by CD locally. If you want to sell it digitally worldwide, you do have to leave Iran since itch.io, Steam, GOG, etc, requires tax information, i dont think Iran will accept what you did as legal because these are US business and you dont have a business license.
