Intuitionism is just disallowing the law of the excluded middle (that propositions are either true or they are not true). Disallowing non-constructive proofs is a related system to intuitionism called “constructivism”. There are rigorous formulations of mathematics that are constructive, intuitionist or even strict finitist.
What point are you responding to?
THe parent of my post referred to disallowing non-constructive proofs, which is not a feature of intuitionist logic but of constructivism.
