I think that it is easier and less confusing to say “An unguyed tower than can
be guyed”

What I mean with "a guyed tower that can be unguyed" is that the guy wire just
adds strength to an already strong structure. A self-supporting tower can stand
with no other support. That's the case with my tower. By adding guy wires you
add, in this case, more strength to the tower so it can sustain more wind. If
there is no, or just little wind I can remove the guy wires without the tower
tipping over. So, "
a guyed tower that can be unguyed" is a self-supporting tower that has been
equipped with guy wires.
I hope this is not too confusing,

I don't have a problem with guying a self-supporting tower IF the guys have
very little tension on them (less than 40 or so pounds). Tower strength comes
from the legs - the more tension you put on the guy wires, the more compression
you put on the legs thus decreasing the capacity of the legs to support the
tower. With a small amount of tension, you're not trying to hold up the tower -
just restrain it from wind forces. With little or no tension, you could be
subject to wind slamming - a violent and potentially fatal condition.
What is a guyed tower that can be unguyed per your comments above? I'm not
sure what that means.

It's not weaker - it just has potentially less capacity.
