It does seem to defeat the whole premise of VCRA if anyone can bypass it for £20
It is just a legal loophole, that is what it is
Although arguably, VCRA is only a deterrent really, if one is determined to do crime they can rattle can a two-tone with a £5 can of black paint
And if you are really just an airsofter playing legitimate airsoft, I have to agree £20 is less than three games of rental which costed me £90
Although the three rental games actually helped inform my first purchase so it can reduce the risk of wrong purchases, if someone jumps the gun and invest in something but later regret it, that is going to cost more than the £70 difference (worse if someone decides airsoft isn't for them within three games)
So I guess (as a new player) if you are certain about the RIF you want and not regret it, £70 is £70
Of course it doesn't apply to older players who already have their own RIF which is just a matter of playing another three games vs £20 bypass, in this case I don't see it as much of a problem
The only scenario where this might become a problem is if someone uses the £20 bypass to get an RIF and then do a crime, which might make the court examine the "standard of proof of defence" question i.e. is a photo sufficient proof of "organisation and holding of permitted activities" (as per Defences to an offence under section 36 of the 2006 Act or under paragraph 4 of Schedule 2 to that Act).
If a photo is sufficient, the loophole will stay.
If a photo is insufficient, the loophole is plugged, but the court will have to say what is considered sufficient.
And arguably a photo should be enough proof as this is probably a common standard of proof in other areas of laws.

PS on second thought, a photo alone is probably not enough, the retailer also needs to check a photo ID to make sure it is the same person in the photo, so the person should really be identifiable in the photo, along with the clear indication of the nature of the activity itself
