> We tend to make a strong distinction between Natural and Legal Rights[1] and to group the Constitution into the latter category
The framers debated the inclusion of the Bill of Rights in the US Constitution for the simple fact that enumerating the rights made them appear though they were "granted" or in your words "Legal Rights." Furthermore, just by entertaining the idea that they should be explicitly enumerated, called into question whether they were "inalienable". However, they fully believed that those first ten amendments were "Natural Rights". In the end, they felt that enumerating them worthy, and given how the amendments are treated/respected/discussed and the litigous environment today - I'm glad they did.

No, they debated them because any enumeration would fail to be exhaustive, and they wanted to avoid omissions from negating rights. There was no mistake on either side that the rights written into law would be legal rights, even if they were motivated by conceptions of natural rights.
The confusion of the Bill of Rights with a statement of natural rights rather than a set of legal rights designed to achieve goals set by moral principles which include a particular concept of natural rights is a more recent phenomenon.
Yes, the framers did debate whether to include the Bill of Rights, but my understanding is that their fear was that by enumerating some rights it would delegitimize those that were not enumerated. That's why we have a (mostly ignored) tenth amendment.
Plus the Bill of Rights aren't quite Natural rights as I understand them. Half the Bill of Rights (plus the 13th and 14th amendments) are about setting up a Legal Right to a somewhat complex and specific trial by jury system. But you don't actually have a Natural Right to participation in that exact system. You do have a Natural Right to just and fair treatment from your government, even when accused of a crime, and a jury trial is a very good way (though not necessarily the only good way, nor the absolute best way) to formalize that right.
On the other hand, I believe I have a Natural Right to bodily autonomy. If I want to surgically change my gender, or have sex with another consenting adult, or ingest a mind-altering substance with full knowledge of the side effects, then that's my right and the Government should have an extremely high bar to clear in order to prevent me from doing so. However, the fact that these rights are not enumerated in the Constitution has historically been a huge barrier to having them respected, which indicates to me that the framers fears were well founded.
