It's true that there are industries that are holdouts for using fax
(like doctors), and few companies are wise enough to adopt open
encryption standards, like S/MIME (instead fording you to use web sites
or other proprietary encryption for sending secure messages), but there
is no legal necessity to use fax.

It may be coming to a point where it's not possible to send fax messages: many long-distance calls are done via VoIP, which doesn't always have fax compatibility, and many "local loop" lines are also changing over to VoIP, or similar technologies, and not all of those are compatible either.

It's true that the medical-care industry prefers fax over email, but I doubt they are holding out because of tradition: doctors have, after all, been using computerized medical records for over a decade. I suspect that it's a way to cut costs by requiring customers to deliver documents by hand, since few patients have fax machines at home, and demanding fax transmission instead of email saves the HMOs the costs of virus screening and/or remediation.

When you say "legally recognized way" it really comes down to what is
recognized by the law and the courts as a legitimate way to sign a legal
document, and that was addressed by the ESIGN Act in 2000.

Despite verbiage that states simply typing my name on an online page constitutes a "signature", I doubt it's so. Unless there have been legal test of the practice, and applicable precedents are in place, I view "electronic signatures" as invalid without PKI. After all, the essence of a signature is that it's hard to forge, and electronic commerce needs the features PKI offers: verification, non-repudiation, and transactional granularity.
