No one is saying that it's "necessary" for you to get the UVIP, but it is being strongly recommended that you do for reasons already mentioned.
If the seller is reluctant to get you a UVIP himself, regardless of the excuses he gives, then I'd be somewhat suspicious. But hey, it's your time and money.
