I can't speak for all western countries but in my country (France) if the government tried to impose quarantine on the same level as China, I'd expect riots.
People here aren't as docile as Chinese people and don't fear their government. If a city was quarantined like Wuhan with the situation turning to shit, many people would take to the street to protest instead of staying nicely confined at home.
And if the government's repression got too harsh there, you'd get protests all around the country in support.
That's why I haven't heard anything from my government about potential large-scale quarantine. They know that here it probably would make the situation worse.
