> Handley’s simulation suggests that the project will be most appealing to high-frequency traders at big banks, who might be willing to fork out large sums for dedicated, faster connections.[1]
So even if LEO is more expensive, which it will not be, the expense will be covered by large financial firms.
Also companies like AWS pay a lot of money for bandwidth between their datacenters. Once Amazon's satellites are up and running, AWS will continue to need government permissions to build new datacenters (including ground stations) but will not need to interact with any other company for bandwidth. Improving AWS' profit margin for existing datacenters.
Finally, today AWS cannot build a datacenter in low cost areas because they need great internet connectivity. However, a LEO constellation enables them to build in significantly cheaper locations (think about the land/construction costs in Moldova vs Germany i.e. 6x reduction[2]).
These alone are huge benefits that outweigh the costs, but adding general purpose internet traffic will only improve cost effectiveness.
