I think we have to distinguish slack from freedom or indeed total absence of constraints. When I was younger I was fond of saying that freedom is overrated, because all this striving for freedom comes at significant costs of its own. Deliberately limiting oneself can indeed create some slack. For example, I don’t have a driver’s license (initially for environmental reasons), which might look like a lack of freedom to go where I want. But I noticed that this doesn’t take notable options away (I live in a big city with good public transportation). I and my environment adapt and if I really need a car I can take a taxi from all the saved car costs. Maybe not the best example to illustrate this, but the best I currently have on offer :-)
