Would you rather them able to blur your house without you telling them your address?
If you have a Google account, I’d assume your address is already known. The form only asks for clarifying details and an email address.
How did they know my address from having a Google account?
Recording it as home in Google Maps.
So many different options: Shipping confirmation emails, IP addresses of connected accounts, GPS of frequent locations (i.e at nights when you're presumably sleeping), phone number for 2FA that can easily be reverse-lookup'd to PII databases, etc. etc.
