But no one is talking about trading one for the other. OTOH you
*are* talking about trading copying for read-only aliasing. And
you have not made an argument about how that buys appreciable
added safety.

Unfounded does not mean untrue.

Many ideas seem self-evidently good or right until you try them
in practice. That does not usually prove them wrong, but will
often reveal caveats that weren’t casually apparent beforehand.

Has there in fact been pervasive use of making things read-only,
such that people have found all the problematic interactions,
edge cases, annoying inconveniences and so on? To my knowledge,
this is not the case, so “unfounded” it is.
