I think there is a lot of value to blowing up your Arduino for reals. When you blow up a couple of Arduinos, you'll tend to force yourself to learn very quickly why it is happening and how to avoid it.
What is so bad about "blowing up a capacitor" or "burning yourself with a soldering iron"? Capacitors are a few cents, each. Buy them in bulk and never worry about needing one again. Soldering iron burns are easy to avoid if you have spent any time in a kitchen.
I feel like this is missing a big point. Arduino is the safe, easy entry point to learn electronics. The danger is miniscule, and whatever danger that is there, is part of the learning process. You need this as much as you need a rice-cooker simulator.
