That's because /etc/profile does it explicitly:
PS1='\...@\h:\w\$ '
if [ -f /etc/bash.bashrc ]; then
. /etc/bash.bashrc
fi
Read and understand the OPTIONS and INVOCATION sections of the bash man
file.

No it doesn't. env runs a program in a modified environment. bash is a
program where set and umask are run by bash, not env.

No, we really can't instruct for every possible combination of lack of
knowledge. Having enough background in Linux to solve simple usage
problems like this is really a prerequisite for LFS.
