This line of reasoning doesn't fly, it's like saying someone should run for president if they don't like the way things are. Just because someone has good ideas, it doesn't mean they have the time or platform to create the level of change they want to see. Realistically people are generally just able to affect their communities, and hope from there things will spread.You should create it yourself
People house rule because they think their rule is better and make the game worse. And then complain that the rules are bad.
Depends how well thought out the house rule is. Many certainly do make the game better. Other times, maybe not enough thought was put into it, or there is disagreement between players about it. Ideally the rulebook itself is good enough that not many house rules are needed. The problem is even if someone has an "objectively better" version of a game, it might include so many changes that it's just too hard to get a whole group on board; they don't want to do the "homework" of deviating from a published book that will be the standard for other playgroups.
