Why can't I use “$whoami” as a variable in “chown $whoami path”?

Why doesn't this work?
[my_user@archlinux ~]$ sudo chown -R $whoami /my_folder/path1/path2
chown: missing operand after ‘/my_folder/path1/path2’
Try 'chown --help' for more information.
[my_user@archlinux ~]$ sudo chown -R my_user /my_folder/path1/path2
[my_user@archlinux ~]$ $whoami
[my_user@archlinux ~]$ $whoami
But:
[my_user@archlinux ~]$ whoami
my_user
How to use the result of whoami in sudo chown -R?
bash variable

The variable $whoami does not have a value. You may give it a value with
whoami=$(whoami)
but in this case you may want to use the command substitution $(whoami) directly:
sudo chown -R "$(whoami)" /my_folder/path1/path2
A command substitution, $(...), expands to the output of the command within (minus any trailing newline).
The variable $LOGNAME (and/or $USER) should have the same value as is returned by whoami, which means that you could also do
sudo chown -R "$LOGNAME" /my_folder/path1/path2
