The dome is so much more than a dome. It is a whole work of engineering, from the way it was assembled and installed to the internal structure itself. It is built in two layers. The inner one deflects radiation and heat back into the core, in the middle there is a cooling layer, I believe they even use liquid cooling to ensure the temperature difference between the inner hot and the outer cold layers are not too drastic which could cause thermal expansion and damage. And then there is the outer layer, designed to withstand heavy winds and harsh climate conditions. Just piercing the outer layer would have damaged the coolant middle layer and ruined a large amount of engineering work that went into this structure. The dome was also literally built in such a way that it was assembled a few meters away and then slid over. There is no real practical way to fix the hole that appeared. There is no sufficiently tall ladder or sufficiently stable helicopter for this work. Especially in the middle of a war. Putin should be sent to The Hague for just this, but there are many more reasons too.
