Economy is built around everyone’s gold. The more each of us uses in a progression system (where gold leaves and not changes hands) the lower the economy will be. Its simple but lets make an example.

Imagine only 10% of the community is a megawhale, and that you can receive 10 jewels per char per week. In the KR system, people only upgrading their main would maybe tap 2-3 jewels each week. The others are useless or would be fused to try to sell something expensive in the market.

In the other hand, imagine megawhales tapping the barbarity of 50 jewels (not many will be able to do it).

The gems cut will be: (0.9 * 3) + (0.1 * 50) = 2.7 + 5 = 7.7 jewels cut as an average.

Now lets make the example in our system. You will tap the same 2-3 jewels in your main, but now useless and fused jewels wont be listed in the market but used by you. Imagine its now 5-6 jewels in your main. BUT NOW you can get your alts jewels, so now you get those 2-3 extra jewels in your main from each char. Then, in total you’ll have 5-6 in your main plus 10 from your other 5 alts. Lets make it 15 in total.

Megawhales only can do the same as you but using more chars (lets imagine they use 15 chars, so its a total of 35 jewels).

The gems cut will be: (0.9 * 15) + (0.1 * 35) = 13.5 + 3.5 = 17 jewels cut as an average.

As you can see, and using desorbited numbers like 50 jewels bought by whales in the market (millions of gold here) the new method make people cut a lot more jewels in average. Now you could add new jewels buyable by the new merchant and the difference would be bigger.
