This is a question of resiliance — how good will your system cope when the executive is trying to get rid of democratic principles?
I think nearly none of the modern democracies is perfect in terms of systemic rules and procedures when it comes to resilience. In both the UK and the US you see the institutions struggling and in their struggle the fault lines become visible. Maybe I am just overly cautious or alarmist, but it is incredibly hard (and potentially bloody) to get democracy back once it is gone.
A good system of societal rules increases individual freedoms instead of decreasing them. A bit like roads force you to take certain paths (thus decreasing your freedom), but enable more vehicles to take that path and do so with higher comfort and speed (thus greatly increasing the freedom).
Overregulation can of course negatively impact freedom, but so can underregulation or the inability to enforce rules.
