Yes, but that is a function of satellite density or so the argument seems to suggest. SpaceX is launching rockets multiple times a week and has put more satellites into orbit that any entity in the history of human kind by an order of magnitude or more. Betting they won't be able to meet these speed goals is not a rational conclusion.
If you read through the decision, the reasoning is all there, it's absolutely rational. What's _not_ rational is preferring personal anecdotal experience over the aggregate analysis.
