The days of merely protecting one's property are long over. At least in the US real estate taxes pay for many services unrelated to safety of the property. For example, closing a real estate tax funded senior center is unlikely to result in an increase in crime. Maybe the seniors themselves would be more vulnerable without a senior center, but I fail to see a general crime spree resulting. If anything the seniors would be watching other people's property and call the cops at any sign of potentially suspicious activity.
