Suppose the people who hate free to play games win the argument and get rid of microtransactions. Suppose they change the laws so you have to get your looter shooter Destiny/Anthem/Division dopamine drip for one fair fixed price. So you're grinding hundreds of hours to get better armor, but you aren't spending more money. Just time.
If it’s a single fixed price, what is incentivizing the developer to make the game more addictive? Purchasing the sequel? Wouldn’t the developer instead be incentivized to make a game with novel and compelling gameplay that isn’t necessarily addictive?
