Hiding the "where" is important too, even when they know the "who".

In terms of Coinbase relation it changes nothing. It is just good practice to have it on all the time for all internet activities. If you use it like that then how can you even turn it off for Coinbase if they ask you politely and you agree? VPN is either on or off. There is other state.

If anyone tell me I cannot use his services because of VPN they can go fuck themselves.

You might want to hide your current location, or prevent your ISP knowing you connect coinbase.
