You think that someone will break into your house and attack you because they know you bought a ledger? Most of ledger users have more valuable stuff in their houses than on their wallets. How are you going to know if:

The buyer bought it for themselves and not to give away or sell?
The buyer holds a lot of coins?

You could end up breaking into someone's home and risking getting shot or stabbed to learn that they sold it, gave it to a friend or have just $1000 or something like that in cryptocurrencies. The wedding rings most people have on their fingers all the time can be worth more than that.

I have a ledger and it wasn't bought on their site so I don't care.
