I think you may be confusing Starship and Falcon Heavy. Falcon Heavy is a production launch vehicle that has launched payloads for NASA, DoD, etc. at this point.
It’s been launching operational payloads for 6 years now.
SpaceX might be pricing Heavy launches high enough to dampen demand until they can support more launches.
(Are you sure that you are talking about Falcon Heavy? The heavy launcher which is basically 3 Falcon 9 boosters bungee corded together[1]. First launched in 2018. And not Starship which first launched successfully in 2024?)
1: Not really. Just a joke. Before someone nitpicks
