I've never moved more than a few thousand dollars around at a time... but you absolutely could move that much into coinbase and withdraw into a US account. Might have some forms to fill out, might have a small waiting period. Will have to send coinbase your US ID etc. But i would be surprised if you had too many issues.
Thank you, that is helpful to know for future reference if I'm ever in a similar situation. I have also moved smaller amounts in the past without much problems (though this was years ago), but you are probably right that this too would have been doable.
