This is really bugging me when I read this forum. It's a very prevalent misconception.
When you do an SBC that costs 100k or more, you didn't just remove 100k worth of coins from the market. You removed cards that were VALUED at 100k or more. The only coins you ACTUALLY removed from the market were the discard values of those cards, which technically don't even exist if you don't discard those cards. You removed the POSSIBILITY of those discard coins ever coming to fruition. What REALLY happened to your coins is that they were just transferred to someone else when you bought their card to put into the SBC.
Put another way, if I buy some magic beans from you and pay you with my money, but then proceed to throw those beans into a bottomless pit, did the money I pay you go with it? Of course not.
