The distribution of goods will probably be maintained until others lower the gap over time.

Using the metric of “4 earths of resources” is confusing and easily misunderstood. What that metric means is that if everyone were to have the same consumption as the average U.S. person tomorrow, we wouldn’t have enough renewable resources to meet demand.

This is not an insurmountable problem. It just requires increasing production everywhere else. Your cited metric isn’t a stat on the theoretical limit of global production, it’s one that describes its current limits.

The stat also factors in carbon emissions, but this is also easily addressable in a world where labor and maintenance is cheap.
