Because if I want to write something eg. into a file, I don't want to
first to have to create a dynamically allocated string, just to write
the contents of that string to the file and then destroy that string.
I want to write directly to the file.

Because it's useless and inefficient, fills caches with useless
garbage and causes memory fragmentation. In the worst cases it consumes
a lot of RAM for no good reason.

Consider what happens if what you want to write to the file is, for
example, three large strings, which you want to write to the file
concatenated. What possible benefit would there be in first creating
a new string that's a concatenation of those three strings, and then
write that string, when you could just as well simply write the three
strings directly to the file?

I would ask you the reverse: Why dou you want to create a string first,
if you could just write to the file directly?

to_string() does not write to a file.

Because if I am, for example, writing a bunch of strings to a file,
I don't want to first concatenate those strings to a new string in
memory before writing it. I want to write the strings directly to
the file without that useless middle step, which is just a waste
of time and memory.
