Although it did occur to me you might not have meant "lazy" by "unbudolike." Nonetheless, I would say accidents are one of the foremost teachers, so strictly speaking it seems like a good idea to "[Do things based on accidents happenning]." I agree it's a bad idea to allow yourself too much slack though.
I can see how "no tsuba" could be a good specific training method too, though. As you said, showing why the blades shouldn't slide unless you specifically want them to slide is pretty useful. If the practice isn't too forceful/vigorous it wouldn't hurt so much, but it would create a visceral connection when contact with the hand is made, which is I think, invaluable, if not entirely crucial, to the budo learning process.
