People turn to the internet when real life is not very stimulating. Banning the internet does not remove that problem.
That being said, it's a small village, and it's only for a few hours. I find the measure authoritarian, but then again my context is that of individualism and urban Western culture. The village did agree to it in a communal sense, and being less reliant on entertainment could make life better there. We would have to know about more about the community and its inhabitants.
