Not my opposing view on sensing, but here's one from Shared Spectrum Corp:

"With regard to TV White Spaces reconsideration issues in particular, we stressed the importance of retaining a sensing requirement, at least as an alternative interference avoidance mechanism, for television band devices (TVBDs).

The elimination of the sensing requirement altogether would impact deployment of un-tethered or ad hoc networks and it should be left up to the marketplace to choose which interference avoidance approach, or both, provides the best performance and protection.

Spectrum sensing data could also provide a valuable, independent check on the accuracy of localized information
regarding protected operations contained in or missing from the geolocation database or in the likely case where the geolocation of the TVBDs cannot be accurately determined (e.g., indoors).

We also raised questions about recent speculative and unsupported assertions that sensing would be too costly to make TVBD deployment economical, especially since SSC’s sensing approach is completely software based.
At the same time, we note that the marginal cost of implementing the geolocation requirements (including
the fees charged by database managers) is currently unknown."
