I'm sure self-validation plays a large part, but the other reason is because local critics of lockdown are using Sweden (which at least here in Southern Europe is generally associated with good governance, as opposed to ours) as an argument for their side. So even people who agree with you that it's too early to tell from the numbers, but who think the lockdown is in theory the best approach, feel forced to write stuff showing how bad things are going for them.
