Holy cow, silly rabbit. The inflation of doge is less than the new gold being smelted each year, and far less than the number of diamonds mined. 
Whoa, that's a bold statement. You got any facts saying that the supply of new gold smelted per year or new diamonds mined exceeds 5% a year?Doge is 3%, and gold is just over 1.5%. On the books. Everyone in the biz knows diamonds are worth nothing, debeers has been sitting on mountains of them trying to hide them all while fools get married.
Btw the real inflation rate for most 'western' countries is more than 8%, pushing 15%. You have to look at food prices. Children with no understanding of economics should not baulk at something they perceived as baulkable just to baulk. Dummies.
Look it up and learn. People will spend recklessly with thousands of doge but have not, historically, with gold. So adjust for that and add common sense.
