a $5 salvation army bargain bin cast-iron "huffy" frame, if it fits, will make
a decent touring bike when built up with solid wheels and components.

the frame may be heavy, but 99.44% serviceable and guaranteed not to break.

on the another hand, a $5000 hand-built titanium touring frame built up with
the carpy components that came off that huffy would be an exercise
in frustration.
