This is the same thing as economic sanctions - it targets indiscriminately and it targets the wrong use case, but proponents will say it encourages people to press against the real problem and demand change.
Just like, say, random Cuban citizens do nothing to meaningfully harm the US, random houses in urban California aren't where water waste is worst. The real problem is agriculture and water rights that disappear if unused, encouraging farmers to pour water in a ditch so they don't lose their rights.
If you believe broad based economic sanctions work, you should believe this works under the same principles - the citizens will be so annoyed they have to deal with this they'll get the government to change.
If you don't believe this will work, then one must assume you believe broad sanctions wouldn't work either.
