97.307 doesn't apply to FHSS or DSSS. The applicable section is 97.311.
Anyway this isn't the place to discuss rules in my opinion.
I disagree. Since the rules restrict what we can do on the air and the bandwidth characteristics of the emissions involved I think it's very important for hams to understand digital communications in the context of the rules, especially since hams in the U.S. may actually be under more strictures than those in other countries.
I don't mean we should start talking about rules and what needs to change on this list but when someone raises a rule stating 100kHz is the maximum bandwidth allowed, it's important to point out that spread spectrum communications, and the applicable rules that allow it, specifically depends on bandwidths greater than that by at least three orders of magnitude.
