I want to start by addressing the 'it only really effects 45 people' argument.
People make decisions on attending events like Regionals based on prize support. People make decisions on purchasing cards based on which events they will attend. By spreading out Regionals across three different formats, retailers will see the sales of single cards improve at two times during the year that they previously did not. Players can no longer wait until States to try and invest for an invite like they could under the ELO system. Just comparing the old ELO system to the 3 Regional Championship Point system has improved the health of the game for those selling singles.
This is good for TPCi, and this is good for players, since more retailers should be willing to sell singles as the market conditions for them improves. People who don't even play the game are effected by these decisions.
Also, players will distribute their resources logically. While few may attend Regionals with no expectation of winning in Masters, many players will be realistic that their chances of winning are in fact quite low. They probably have that one celebrity level player they can't imagine themselves beating. If a player could drive to a single Regional for the day, and would need to stay at a hotel for two others, they might instead choose to simply skip 2 Regionals and put that money toward Nationals. It is the safe bet. If I have fewer friends to stay with at events, it effects me as well. Either I'm paying more, or I'm forced to stay with people who I don't know as well. Maybe they're nice people, but the minimum difference is that I'm forced outside my comfort zone, the maximum is that they steal my cards in the middle of the night.
Frequently attending events helps to remind players, especially Masters, how much fun this game is. Discouraging people from doing that makes them wonder, 'why bother?' to some extent. The potential to win something is exciting, valuable, and has an effect on people outside the eventual winner. There is no insisting your way out of this, I've lived it.
'contact the higher ups and get some reasoning/solutions'?
you're assuming that this decision is up for popular vote of the players....i'm pretty sure it isn't.
I'm not sure this is really going to sway anyone.
