You're soft selling the situation. Emigrating to evade the draft is a crime.A citizen can emigrate.
If returning to the US, draft evaders & deserters faced prosecution.
(Eventually, amnesty was granted for the former.)
So to treat it as normal emigration is highly misleading.
My diagnosis....
If you'd been then & there, & faced being drafted,
these would be things you'd keenly remember.
To you, it's just something to quibble over because
you give inadequate weight to important considerations.
Note....
A diagnosis is not an ad hominem argument.
