I mean, given that you can lie to them, it pretty much so is voluntary.
Like I said, it makes me uncomfortable too, but in the end I really doubt they will use the information for anything other than contact tracing and given the general level of competence of our government, I doubt they will even use it for that. And they already have a lot more than you name and phone number anyway. Hell, they could use the crime cameras to track people by their licenses plates or put out photos of people who were in an area with an infection. (I find that much more disturbing.)
It's not ideal, but it's better than doing it at every business and in the end, you really don't have to do it since you can give them a fake name and number if you choose not to do something to help with contact tracing. And, as has been mentioned before, this is less intrusive than them just getting a warrant, or not bothering to get a warrant based on exigent circumstances, to get the information from any number of other sources like your mobile phone, debit card, GPS in your car, etc.
I get the principle of it all, but I'm finding it really hard to get worked up over giving a restaurant my name and phone number which I have done many times in the past.
But, I'm curious, do you answer the Census?
Also, LaToya mentioned that the Archdioses will be having people register on line and reserve spots to go the Mass? And while they are not required to make those lists or keep them, she noted that those lists could be used to contact trace if necessary. I assume this has been agreed to by the Archbishop, but I'm not certain. So, will you be attending Mass?
Finally, I do you think some right is being unconstitutionally violated? If so, which one?
