I find this argument thoughtless. Those of us who don't own our own homes are often prohibited from making these kinds of modifications.
Also if you have enough $$ worth of mining equipment to necessitate a dedicated 240v circuit, you probably should have had home ownership higher on your priority list.

This is a little pushy .. next time, if you're a miner, you should own a boat too, have 5 kids and live in a mansion, if one can find a good enough reason. Three years ago you'd find ONLY geeky guys with their GPUs/CPUs in the landscape. Now we jumped to data-center grade stuff, and I don't see the need to own a house yet just for "being a miner".
