Trading not avaliable for 3 days

I just bought ten coins to buy some gold for my first character on this server, but I can't trade until I wait three days after setting up 2FA. I would be glad if I could buy gems and enchants before the weekend so I can go to arenas. Is there any chance to take off this waiting time?

Taking it off would defeat the whole point of it's existence. Take it easy for 3 days, no other way.

but it doesn't make any sense does it?

It makes perfect sense, it's very effective security measure.
