You could make that argument about many things. Like Forum posting.
I've met a number of people who I would never have interacted with otherwise via baseball. I'm not on the top list posted here but I think it's a good opportunity to kill time and make a modest sum when looked at as a per day average.
If you're going to change things you could make the investment portion change. Every x games you need stadium maintenance. Or every x days.
But it's not super game changing or providing an unfair advantage that isn't available to anyone else.
On the other hand, we've got a large thread about this tiny issue that affects few people while there's a literal game breaking bug that to my knowledge still isn't fixed. Baseball works exactly as it was designed. War currently isn't. Bigger fish to fry here.
