(Bedrock) A way to only buy the game once

Hello, my idea is that when you buy the minecraft pe example game in the play store if you with the same account you start in the windows 10 microsoft store you already have purchased minecraft for windows 10 because they are practically the same, the same for ps4, ps5, nintendo switch, Wi U, etc. This is because many people cannot afford to buy the game over and over again with each console. thanks for reading and maybe understanding.
