Governments ("States") have never had much trouble making laws and courts to control the citizens.
The idea that a state should have some rules to follow was slow coming. Until quite recently it was thought that what a state did to people inside its own borders was its own affair and nobody else's. For example a government might think it was a good idea to sterilise or euthanise the mentally feeble or deranged, or those physically disabled; or to lock up people according to their religion, or to deport citizens of unwelcome ethnicity, or to torture people to make them confess to crimes. The citizen had no right of redress against a government doing so. The UK directed its lawyers to draft the ECHR in an attempt to give governments rules on acceptable behaviour, and to give citizens a chance to seek redress within the country's laws or, failing that, outside.
So if you are looking for rules telling people they shouldn't murder, or rob, or park on yellow lines, you won't find them in the ECHR. That's not what it's for.
If you are a person who approves of torture, imprisonment without trial, or slavery, then it must seem very irksome to be told you shouldn't do it.
Sadly I have never yet found an opponent of human rights who will admit which rights he wishes to remove.
