<i>"intentionally accesses a computer without authorization or exceeds authorized access, and thereby obtains ... information from any protected computer"</i>
It doesn't say "intent to commit fraud" or even "intent to obtain information". It just says "intent to unauthorized access". Negligence and recklessness count as intent, so accessing a computer without caring whether you had authorization or not is still "intent".
When the CFAA was written in 1986, all access to computers was explicitly authorized. Then the web happened, when people started recklessly accessing computers without caring whether they were authorized, and everyone was in technical violation of the law.
