The thing is, is that not EVERYONE is going to use boosters and obviously that wouldn't be fair for players that choose not to. In order for a good game, everything has to be equal in terms of the equipment. Rather than boosting to make it more exciting, it's better off that these players actually train more and improve themselves rather than use boosters (in ITTF tournaments) to give them the upperhand. Now THAT is much more legitimate and exciting in my opinion!
However, because you're not one of these professionals, of course in your perspective it would be much more fun and enjoyable (It would be hella enjoyable even for me since I know I can give the ball so much more speed) but you have to remember that Jun Mizutani is doing this in terms of professional players and the fair play needed in such important tournaments!
FYI, Marty Reisman, a Ping Pong legend back in the day said that back in the days, there was no speed glue, no serve hiding, no boosters, NOTHING, just a wooden paddle, and that was all he had to rely on to win. He said that these days, players and others are finding ways to give them a upper hand and it isn't fair, but back in the days it wasn't like that at all!
