A constitution is only as good as the quality of the institutions that exist to defend it. Undermine the institutions and a constitution is no more worth than the paper it’s printed on.
In the Republic of Ireland we have a relatively good constitution, fairly active, that has a vast hole in the first paragraph of Article 45:
ARTICLE 45
The principles of social policy set forth in this Article are intended for the general guidance of the Oireachtas. The application of those principles in the making of laws shall be the care of the Oireachtas exclusively, and shall not be cognisable by any Court under any of the provisions of this Constitution.
This obviously both deliberate and insane. We should remove it. It is the biggest institutional flaw in our constitution. But Bunreacht na hEireann is worth so much more than the paper its printed on, or the jurisdiction of the courts it defines. It is the code of the country, the will of the people, enacted, modified and attained. It is the source of our of our law, our shared hope, and our sense of gathered self. We are our constitution, we are free.
If so, this is not uncommon in constitutions, the term in the italian legal system is "autodichia" (something like "self-justice").
If you didn't have this then the law would be decided by unelected officials.
If you don't want a part of the constitution to be enforced, why should it even be there?
2 The State shall, in particular, direct its policy towards securing:–
i That the citizens (all of whom, men and women equally, have the right to an adequate means of livelihood) may through their occupations find the means of making reasonable provision for their domestic needs.
ii That the ownership and control of the material resources of the community may be so distributed amongst private individuals and the various classes as best to subserve the common good.
iii That, especially, the operation of free competition shall not be allowed so to develop as to result in the concentration of the ownership or control of essential commodities in a few individuals to the common detriment.
iv That in what pertains to the control of credit the constant and predominant aim shall be the welfare of the people as a whole.
v That there may be established on the land in economic security as many families as in the circumstances shall be practicable.
3 1° The State shall favour and, where necessary, supplement private initiative in industry and commerce.
2° The State shall endeavour to secure that private enterprise shall be so conducted as to ensure reasonable efficiency in the production and distribution of goods and as to protect the public against unjust exploitation.
4 1° The State pledges itself to safeguard with especial care the economic interests of the weaker sections of the community, and, where necessary, to contribute to the support of the infirm, the widow, the orphan, and the aged.
2° The State shall endeavour to ensure that the strength and health of workers, men and women, and the tender age of children shall not be abused and that citizens shall not be forced by economic necessity to enter avocations unsuited to their sex, age or strength.
"The judicial power of government of those courts includes the power to review the compatibility of statutes with the Constitution and to judicially review subordinate legislation, decisions or actions of the Government or State bodies with a view to determining their legality and compatability with the Constitution, and principles deriving from the Constitution such as due process" [0]
I don't understand how Article 45 is interpreted but it's clearly not seen as a loophole where the Oireachtas can be the final arbiter over whether its laws are constitutional.

Of course, an institution won't survive a certain percentage of its members being malign. The stronger the institution, the larger that number is.
To give some ideas of the mechanisms that make this possible, internal reviews are one of the most powerful forces for making sure that rules established yesterday are still respected by people who join tomorrow, even at the very top.
There are plenty of countries that have the same nominal separation of powers, guaranteed by a constitution and a Supreme Court, but where the nominal separation of powers matters little in the face of political games. Hungary and Poland are relatively well known recent examples of countries that have subverted strong constitutional guarantees by inventing exceptions or finding reasons to oust people who are opposing political will for institutional reasons. In more corrupt states it can happen more egregiously.
A big problem, especially in young states, is the natural tendency to dislike red tape. Institutional power is all about red tape, though - doing something through the proper channels, with the proper oversight, even if it takes 3 times as long and costs twice as much as it should. This is the biggest hurdle that a young democracy has to overcome - learning to trust the apparent inefficiency of complex institutions (and knowing how to reform institutions that really don't work).
The actual structures of power have changed quite dramatically roughly every 70 years in the US, from getting rid of the idea of states as sovereign with the Civil War to gutting the interstate commerce clause of all meaning under FDR or there President arrogating all war making powers to himself against the quite explicit provisions in the constitution. Most recent huge change would be either the administrative state after WW2 or getting rid of freedom of association.

And I doubt either of us have done a survey of dictators; a lot of them probably do just ignore the local constitution.
It is important to remember that people who think we should follow the intent of a 100 year old law (or even a 10 year old law) are a tiny minority group. The majority of humans are here-and-now, what-looks-like-a-good-idea-today?, what-do-I-see-in-front-of-me people.
