some gismu queries

Some queries on some gismu.

(1) Why do so many gismi have a conditions sumti, when we
(quite rightly) have {va'o}? Let all conditions sumti be
deleted. I reckon if this was put to a vote there'd be an
overwhelming majority in favour. Same for {ma'i} replacing
by-standard places, etc. I remember Jorge & others having
made the same point, but I forget if there's any good
argument against it.

(2) Is
   jdari        jar     firm    'hard'
   x1 is firm/hard/resistant/unyielding to force x2
equivalent to {tinsa fe [inwardly]}?
   tinsa                stiff
   x1 is stiff/rigid/inflexible/resistant in direction
   x2 against force x3

(3) Is there a difference between:
   kavbu        kav     capture  'catch'
   x1 captures/catches/apprehends x2 with trap/restraint x3
   pinfu        pif     prisoner 'captive'
   x1 is a prisoner/captive of x2, restrained/held by means/force x3;
Or, more specifically, is {kavbu} {x1=p1=k2 pifcoa x2=p2=k1
x3=p3 tahi k3}?
