More importantly, money, at global scale, doesn't solve scarcity issues. If there are 100 apples and 120 people making sure everyone has a lot of money doesn't magically create 20 more apples. It just raises the price of apples. Building an apple orchard creates apples. Stargate is people betting that they are building a phenomenal apple orchard. I'm not sure they will and an worried the apple orchard will poison us all but unlike me these people are putting their money where their mouth is and had thus larger inventive to figure out what they are doing.
On global scale if you have 100 people and 150 apples but apples are on the opposite side of the globe it is not like you can sustainably get those apples delivered all the time.
Getting 150 apples once is better than nothing but still doesn’t fix the problem.
