You don't need high bandwidth density for this kind of usage. A single downlink in an area connecting to some datacenter in LEO could be useful for latency sensitive stuff. Then on top of that there's a huge market hasn't been cracked yet which is automated planting of crops. It needs 1-2 cm of accuracy to be useful and the best in the market currently is at 6cm. Plus all kinds of IoT stuff and long-range latency sensitive backhaul( in which case LEO constellations win because the distance is actually smaller due to the low number of trans-oceanic cables and the high number of switches along the way).
