Big difference between the two. In freestyle, when attacking, you could give up two points for back exposure even while completing your TD. So you were risking 2 points to get 1. They needed to even that out to make the risk/reward ratio event.
Currently in folk there is already a high risk when you initiate contact; you are risking two points to get two. However, in folk if you escape you get one of those points back; so you aren't burying yourself if you initiate an attack and get countered. With a three-point TD, if you initiate an attack against a good counter wrestler you would be taking a huge risk to get that TD. Late in the match you might get more action, but I think you would see even more 0-0 first periods.
Which is why I would favor the official declare each takedown either three points (guy scoring the TD initiated the action) or two points (guy scoring did not initiate the action.) This would encourage aggressive wrestling and punish passive wrestling.
