Who exactly is "forcing" the best players in the world to play on bar boxes? WTF are you talking about. Most pro tourneys are on 9 foot tables, with the exception of the BarBox Championships, which are, yep, played on bar box tables.
And, they don't even have to sign up, they don't have to attend, so even then, who is forcing anyone ?
So, yeah, non professional pool players get to play on smaller tables that hide some of their flaws, and makes the game a little bit more enjoyable. Wow, the horrors.
Well, guess what, my baseball team does NOT play on a field the size of professionals. My god, there would NEVER be a homerun, there would be plenty of triples, because anything over our heads the ball would roll for a mile, and it might take 2 cut off guys from the wall for a play at the plate.
So,yeah, we play on HS fields because that is what we have at our disposal, and it's fun, cause even some of the old guys can still jack one

If you don't have fun at the sport you love and play, there really is no reason to do it. For some, a 9 foot is no fun.
I like both actually, have a 9 foot in basement and play in leagues with a 9 and a 7. I even liked the 12 foot snooker table, but as much as the game is interesting, it just is not enough fun to play because of the sheer size and my sudden transformation into a banger (not that there is anything wrong with that). I mean, do you think folks that play bumper pool should be executed, or just tortured a little
