That's just not possible for now, because Steam/Denuvo only allows 5 new users activation per day so there's no way we will be able to manage the uncountable number of users in the open internet world, but the best we can do is at least give access to the games for every 10-20 new users daily for a small fee
First you said that this allow 5 new users per day, but later you say that you can sell this to 20 people per day.
