No.
In fact, they destroyed lives and livlihoods.
The only noticeable effect was to further aggrandize the totalitarian (total control) impulses already existing in many politicians and members of the administrative state, exemplifying one of our mantras (we have a few): "The people who seek political power are the very people who should most be kept from acquiring it.

SARS‑CoV‑2 suppression and early
closure of bars and restaurants:
a longitudinal natural experiment
Abstract
Despite severe economic damage, full‑service restaurants and bars have been closed in hopes of suppressing the spread of SARS‑CoV‑2 worldwide. This paper explores whether the early closure of restaurants and bars in February 2021 reduced symptoms of SARS‑CoV‑2 in Japan. Using a large‑ scale nationally representative longitudinal survey, we found that the early closure of restaurants and bars decreased the utilization rate among young persons (OR 0.688; CI95 0.515–0.918) and those who visited these places before the pandemic (OR 0.754; CI95 0.594–0.957). However, symptoms of SARS‑CoV‑2 did not decrease in these active and high‑risk subpopulations. Among the more inactive and low‑risk subpopulations, such as elderly persons, no discernible impacts are observed in both the utilization of restaurants and bars and the symptoms of SARS‑CoV‑2. These results suggest that the early closure of restaurants and bars without any other concurrent measures does not contribute to the suppression of SARS‑CoV‑2.
