Inflation doesn't work like that, bud. You injecting a bunch of money into the economy doesn't all of the sudden make everyone poor. (If it even makes it back into the economy; what would probably happen is you spend 35m on the relic bow and it goes right in to some other player's wallet to sit forever. You would have to spread it out amongst lots of sellers to even have a noticeable effect.)
Rich people horde because they view their gil as a stat they need to max out. They're not martyrs who bear the burden of wealth on behalf of the poor or something equally ridiculous.
