The Interstate and other roads would have that written on them as well. All forms of transport are a huge bill for the public. Anyone who tells you otherwise isn't looking at all aspects.
The problem with rail, is that we need to pay for modernization of a system that has languished since commercial air travel took off (no pun intended) in the middle of the last century. Road and air travel haven't had this problem* as they've enjoy plenty of modernization $$s during that same time.
You will be stuck footing the bill on HSR, just like your currently stuck footing the bill for your highways, interstates, roads, airports, etc. It's not necessarily bad or good, just the way it is.
Even with the funding they've received, many local and state roads are still in an inadequate state.
