Section 2 already limits applicability to persons collecting or processing data on not less than 60,000 consumers, so suits brought against neighbors would be (rightfully) dismissed.

The concern about poor precedent stemming from poor cases has some rational sense, but we have the benefit of experience. Empirically it just hasn't tended to play out like that in the case of consumer protection statutes in MA. One reason this doesn't happen in practice might be the limited bandwidth of the appellate process. The SJC could (and likely would) prioritize answering questions about the statute in the context of cases brought by the AG.

The longevity pro-consumer laws in MA provides some good empirical data that cuts against the concern about push-back.
