I strongly disagree with this. "Strictly?" Oh my, no. There's so much more that goes into one's practical ability to exercise freedom. It's why a rich person—even if they were treated identically by the state—is far freer than a poor person. It's why removing hypothetical but mostly useless freedoms (say, the "freedom" to choose my health insurer) can in some cases truly increase how free I actually am (no longer have to spend all that time screwing around with health insurers; no longer as dependent on employment for healthcare, et c).
