"I am a site collection admin on the site"
IMO, This is irrelevant for publishing Infopath form library. If the form (for example, client/Filler) requires a "Full trust" then the security level warning is issued and specified on the client Infopath Designer 2010 which does not know anything about server accesses and then activated on Sharepoint Server 2010 by farm administrator.
And that activation requires farm administrator privileges but not site collection administrator's one.
Also, why are you publishing and Infopath form onto document library but not to a form library?
Is it:
- in Sharepoint\Infopath 2010 ? 2007? 2003?
- in Office 365 (Sharepoint 2010 Online) ?
- browser or client/Filler form?
- etc.
Can you provide step-by-step indtructions in order to reproduce your error?
Update:
I've just checked in Fiddler2 what is requested and gotten back on pressing Next in publishing wizard to my Sharepoint Online (Office 365) site:

The first dialog window of Infopath Designer 2010 Publishing Wizard before clicking Next button for the 1st time:
Update 3:
Going to sleep.
I am on Sharepoint Online (Office 365) site, OOTB. Before that I used on-premise Sharepoint Server 2010 mounted in virtual machine, taken again somewhere from MS on internet, OOTB. Never used claims. AFAIU, NTLM or claims is irrelevant since Infopath uses its own Microsoft Office Protocol and at application level the browser based IP forms communicate with server over XMLHTTP (which is related with necessity to resolve the double hop authentication issues) while client/Filler forms via NTLM (that do not have the double hop issues).
Check that WebDAV is enabled on your server.
IMO Infopath uses Microsoft Office Protocol Discovery so check for compatibility of your server configuration with it.
