Tarkov is a live service game. Which has its own ups and downs. Tarkov has benefits of having some things progress while you are offline. Things happen at the server level while you’re gone.

Not every game needs to be a live service game though or try to use live service features in a single player offline game.

Unless there is a very specific reason in the game mechanics why in game time is 1:1 with real time, it doesn’t make a lot of sense except to be divisive and a discussion point.
