Unfortunately the predicament you describe is nothing to do with ebay they are just having to follow the law laid down originally by the OECD who implemented this along with 38 countries worldwide, the UK being one, so HMRC have to follow suit. If you have nothing to hide you'll be fine, you sell on a private account so if you were for instance to get a nudge letter from HMRC then you would state that items are from around your home, and no further action would be taken.
Personally our details in one form or another are out there everywhere, so I wouldn't let it stop you selling here if thats what you enjoy.
