It would boost the economy and give people an incentive to play the Royal Tunnel too.
All of the Gem Prices are actually pretty reasonable and were lowered a year ago.
The reason the Egg Prices are so high is most likely to keep everything in order and give things value, as a Shiny Starter is much more valuable than an Easy Shiny. Also, you can obtain eggs from the Daycare and Tall Grass, even the Lab in rare cases.
As long as you decrease the prices of everything, not just a couple rarities, then you can preserve that division of value by rarity. Gem collector prices are too outrageous for me to even consider using him as a source of eggs for a hunt. Unless, of course, his purpose isn't to help get eggs for hunts. I don't know what other purpose he would serve, though. Eggdex? But even so, getting one starter egg for the eggdex is too expensive. So I don't know, he's just kinda there.
Edit: And if you take into account the big picture - breeding rates, tall grass spots & time, etc. - then the rarity is preserved anyway.
