A quick google search shows many town ordinances such as this one:

>Guest register. Every innkeeper shall at all times keep and maintain on the premises of hotel a guest register in which shall be inscribed the name and home address of each guest and shall contain such guest's vehicle description and license plate state and number.
"On June 22, 2015, the U.S. Supreme Court concluded in City of Los Angeles v. Patel that a Los Angeles ordinance requiring hoteliers to keep and maintain guest registries and to make them available to the police upon request violated the hoteliers Fourth Amendment rights. "
Hotels need to be on the good side of the police.
That they note that you don't have a right to privacy is the only odd part. It's fairly common around the world to have to present your passport / passport details at hotels for their records. It's definitely not strange that China's hotels would require that.
I think that response is moving the goalpost.
I noted that it's common throughout the world that hotels often require passport details. Your response to that is to change the issue in question to the consequences of non-compliance and away from what you initially presented as the problem ("you must register your passport or state ID").
Is your goal to argue? I don't get it.
His goal is to point out that you said "in China they tell you you need to register at hotels", and when he answered that that's the case in the US and other countries too, you expanded your question to "Does the police show up if you don’t register in Other countries they do in China".
That's normally called "moving the goalposts".
Now you're implying that they have some further motive, or just "want to agree".
Well, they wanted to point a flaw in your original argument (that implied it's somehow unique to China to have you register at hotels). Are they allowed to?

This applies in the US too in most cities I’ve done business in. Some hotels don’t enforce the ordinances, but the hotel is supposed verify who is staying at the hotel, along with license plate numbers of vehicles the guest has. Also, I wouldn’t want to stay in a hotel that doesn’t check rooms periodically (at least once per week), as that is a recipe for meth cooking and hoarders bringing pests into the building and numerous other problems.
