Ansible: Accessing standard user home path while being logged in as root - ansible

Question

I am trying to copy a file using ansible as sudo from remote user home directory ~/bin to usr/local.
This works:
- name: Copy Folder Working
become_user: "{{ ansible_facts.env.SUDO_USER }}"
become: yes
command: sudo mv ~/bin /usr/local/bin
But this doesn't:
- name: Copy Folder Permission Error
become_user: "{{ ansible_facts.env.SUDO_USER }}"
become: yes
copy:
remote_src: yes
src: ~/bin
dest: /usr/share
So even though I use become: yes ansible apparently doesn't copy using sudo. I do get the same permission error as if I would try to copy the file manually without using sudo. The paths seem to be correct. How can I avoid that or is sticking to the first self implemented solution the way to go?
Additional Info
This is part of a playbook that is executed on a server. That server can have ubuntu as its default user, but also any other default user of a Linux distribution is possible. Therefore the default user needs to be read from ansible_facts as I try to do by using "{{ ansible_facts.env.SUDO_USER }}". While SUDO_USER sounds odd this seems to work as I get the expected permission error:
fatal: [localhost]: FAILED! => {
"changed": false,
"invocation": {
"module_args": {
"_original_basename": null,
"attributes": null,
"backup": false,

"dest": "/usr/share",

"seuser": null,

}
},
"msg": "Destination /usr/share not writable"
}
There's also the issue I need to fix that it merges instead of copying, but there are multiple possible solutions for that which I feel are unrelated (for example copying the files from ~/bin/* instead and deleting the folder.
