While I'm not exactly sure what you mean by a "commercially-available,
public encryption system," I think your point is incorrect.

(My confusion is that a commercially-available system is not necessarily a
"public" system, if by public one means public domain. If one means
"published specifications," still not the case. Confusing.)

Howver, the government cannot step in and "control" a
commercially-available product, by even the most liberal interpretations of
the commerce clause. "Tim's Pretty Flaky Snakeoil System," for example. I
can announce it, sell it, and the government is powerless to "control" it.
(Even if it were "public.")

If by "public" you mean an NBS or NIST standard, like DES, then I suppose
the government can in some sense "control" it. (Even this is iffy, IMO, as
I know of no rules saying DES implementations must be approved by NIST or
anyone else.)

Most of the cryptosystems are not under the "control" of the government,
even by the standards of your first definition. Period. RSA is not a
government-controlled system, though it is both "commercially-available"
AND "public" (in that the spec and algorithm are clearly published).

And the talk about "personal use" is misleading, IMO. It suggests that
government can and should regulate use for "business purposes" but not
personal uses. I disagree with this distinction.

You mean the way public key systems in general and  RSA in particular were
invented and devised by non-government folks?
