You do not have to understand all aspects of privacy to realize that governments may have sufficient resources to track your identity and to put enough pressure on businesses to provide information they need.

At the same time, Tor is not the only, the required and the sufficient way to ensure privacy. There are different circumstances requiring different approaches. In many cases Tor will be redundant, in some cases it may be impossible to use, will offer insufficient protection or will actually put the person in an immediate danger, so giving this kind of advice is at least equally harmful as not having full disclosure on logs.
