Is private domain registration worth the extra cost? [closed]

As I said in Domains and 'Private Registration Services':

"Domain Privacy" is a risky thing to engage in -- you don't actually own the domain and don't really have any rights to it if it's registered through a privacy service. Although it's spruiking their own Privacy service, Dynadot's QA on domain privacy services spells out the problems with standard privacy services (you just have to ignore the "and so you should buy ours instead!" flourish at the end).

The vast majority of my domains do not have any sort of "private" registration enabled and I have never, in 12 years, been contacted in a negative way by someone who got my information from the WHOIS database. It used to be a spam source, but I haven't seen that in years. I have the benefit of listing a business address and phone number, but still, no issues. There are a few domains I manage which do use private registration, but unless you have some specific reason to be anonymous (personal safety, etc.), it's not worth the cost in my opinion.
