I think it is a good thing for traceability and ultimately accountability. I have mine microchipped for my piece of mind, just in case he gets lost. A collar can be removed very easily so an ID tag is not the only option. Microchipped and dog tag together are the best combo. As for accountability if your dog causes an accident/ attacks someone when out of your care then you should be able to be traced and held accountable for your dogs actions as you are the owner and the legally responsible party.

Some people complain about a police state and breaching civil liberties, I dont see it that way myself, but then I was all for the national ID card scheme here in the UK as well!

The only reservation I have about microchipping is the increased risk of tumours and cancerous masses forming around the injection site around the microchip later in life but the statistics still make microchipping favourable to not doing so in my opinion. Between 1996 and 2006, researchers found a link between implanted microchip transponders and cancer in laboratory animals.

"Between 1% and 10% of mice and rats implanted with the chips for identification purposes were later afflicted with sarcomas, fibrosarcomas, and other invasive cancers surrounding or attached to the implants. The fast-growing, malignant tumours often metastasized (spread) to internal organs, lymph nodes, and musculature and frequently resulted in the death of the animals." - www.chipmenot.org.uk
