I get:  text = "v=spf1 ip4: -all"

Is that supposed to be relevant to the point, which is that publication
of SPF records affect *all* parties associated with mailboxes using a
domain name (not just the registrant), and -- particularly among large
groups (tens of thousands, millions) -- one size doesn't fit all?  Can
you guarantee that no person who *receives* mail at a domain under will ever wish to *send* mail from a convention site kiosk, an
airport courtesy lounge, a restaurant or cafe, a public access point,

The correct SMTP Server to inject the message via is one provided by for the MSA function. IOW: Tell your MUA to connect to that 

And how precisely does one do that when using a mail kiosk at a convention
site, etc.?

and you are using an SPF Approved/Authorized  
Submission/Relaying Server. If you are not allowed to  use that 
Server (due to SMTP Connection Hijacking on the part of the 
Connectivity Provider then you are out of luck - You should send from 
your Laptop via an Ethernet/WiFi connection).

If port blocking is in effect, that won't help.   That problem exacerbated
by SPF is one of the reasons SPF is harmful to Internet mail.
