Only if you use RSA.  One of the neat things about RSA, as opposed to DH or 
DSA/DSS, is that the same algorithm can do both signature and encryption.

Once we all have our Gummint-issue Citizen-Unit SmartCards with the
Web-Of-Mistrust Hierarchical Certification System, 
people won't be able to use the DSS feature to send you encrypted messages

but you can still use them for signatures, including checking escrow agency 
signatures on your privacy key.
