That's right.

I think that nowadays there are far too many notes around telling people 
not to do this, not to do that, not to do something at home, and so on. 
I mean, if somebody buys that transformer, powers it up and connects 
himself to it, that's his own fault!

I'm not aware of car salespeople having to warn people that it is 
dangerous to drive at 80 mph into a concrete wall, or the like. If you 
buy a car, or a plane, a wire cutter, or anything, you are supposed to 
know how to handle it, or it's your responsibility to learn. Same thing 
applies to high voltage transformers, in my humble opinion.

At age 14 I played with a Jacob's Ladder fed by a 44kV, 5kVA 
transformer. It was particularly attractive to separate the electrodes 
so that it wouldn't ignite on its own, and then light it with a match 
and see the arc climb. I got my fingers to a few centimeters of the 
electrodes. Before doing that, and being the good boy I was, I asked the 
physics teacher at school how far those 44kV could arc, worst case. I 
didn't need a warning note, because it was OBVIOUS that high voltage 
could be dangerous.

Is it that today we have to spell out all obvious risks, so that even 
the most stupid people will be protected from accidents? I prefer the 
relative freedom of my youth! The right to have an occasional accident, 
and learn to be careful without always having others tell us what not to do.

Times seem to have changed. So, when any of you put an amp on eBay, be 
sure to warn buyers that dropping it on their feet can flatten them, 
that lifting it while bending over can injure their backs, that touching 
the antenna while transmitting can burn them, and a loooooooooong list 
of other warnings!  Or better, trust buyers to know what they are doing. 
After all, you simply cannot warn people about ALL possible risks.

Keep in mind that life itself is extremely dangerous: It always has a 
fatal outcome.
