These are all costs of any server hosting business. Other commenters have already shown that $2/hr for a racked 1U server at 400W is perfectly sustainable.
Just because you have all of those costs already doesn't make them go away. If you're cross-subsidising the H100 access with the rest of a profitable business, that's a choice you can make, but it doesn't mean it's suddenly profitable at $2: you still need the profitable rest of the business in order to lose money here.
