As someone who collects Pokemon, One Piece even Digimon and DragonBall cards but just for fun though, not too expensive ones, always raw or by buying a booster box just for the nostalgia and great art work and based on my research i realised the following:
The reason that they don't do what you tell them, which is quite easy to implement, is because even if most of us want more affordable cards and believe that these policies will help, in reality, a lot of scalpers have actually helped increase the demand and value.
Ofc there should be measures against all of these but we can actually do a lot more than we think.
For instance, i keep hearing that some sets and cards are nearly impossible to buy because the prices are like x2-3-4. Simply don't buy, or buy the same card in a Japanese or Korean version. Usually it's half the price. I decided to complete a master set and most of the newest English version ones were extremely expensive. I decided to pursue an older Japanese one, the artwork is great, the cards are half the price of the English ones or even cheaper and booster box was only 60$! In general though, as people we tend to look for the newest sets or the most "marketed" cards, or the most "investable" ones ;)
