There is a process for amending the constitution. If enough citizens feel it should be amended, it can be. It's happened a number of times in the past (although not recently). The big danger is in thinking "we don't like that process, let's circumvent it". Selective circumvention of the law and the constitution eventually will lead to anarchy.
Or more likely to tyranny, as it's those in power that will do the circumvention and they will do that to remain in power. Dictators rewriting the constitution to remain in power is such recurrent event it's practically a cliche by this point.
