Why is the usage of string keys generally considered to be a bad idea?

Yet, so far, I have not found a single such source to also explain WHY it is considered to be bad practice.
Does it depend on the programming language? On the underlying framework? On the implementation?

Is it worthwhile to try to write foolproof data structures?

The problem We need to store data in a table-like way, but we have very strict space constraints (~1Mb per table of 10k+ rows). We store data like this: ID | reviews | factor | score | interval | etc. —+———+——–+——-+———-+—– 1 | 244 | 2.4 | 10 | 4268 | … in a simple […]

Storing in-text metadata in a discrete data structure
