My thoughts exactly. Capacity is a very rough metric for "utility" of the network. Capacity alone says nothing about the node/network's ability to route payments, or even the costliness of using that capacity (i.e. channels with ultra-high fees). It's easy to game the metric in the short term by buying inbound channels from LNBIG, etc. or opening massive channels just to close them later. An efficient node/network would have an extremely SMALL capacity and route high volumes. This competition is incentivizing an inefficient network with high capacity and low volumes.
