I think there is nothing wrong with this approach at all. I am more than happy to have a PDF copy in my email and saved locally on my phone. As someone stated earlier in the thread the advice on whether this is necessary or desirable is ambiguous even within the CBP site itself.

IMHO the disagreements about whether you need an "offline" copy of your ESTA are more to do with individuals trying to prove who knows best rather than what works best for the traveller.

If you want to take a copy, either printed or otherwise, then you should feel free to do so however remember the status will be as of the time you printed it and is not obviously live.
