Are you arguing that Sweden is allowing an uncontrolled spread of the virus? They've had strong voluntary measures in place all year.
In the past month they've also imposed several enforced measures to restrict the spread of the virus, including a limit on gatherings to 8 people, a bar curfew, and they've just closed secondary schools for at least a month.
"Don’t go to gyms, don’t go to libraries, don’t host dinners. Cancel." - Swedish Prime Minister Stefan Lofven.
Despite these measures they are seeing rising hospitalisations. Further measures look inevitable.
Or if not, what are you arguing?
