If later there are complaints from users or the government to add maximum deposit restrictions, each casino will add it to their place to comply with the new regulations. But having this tool in the casino can help gamblers who still want to limit themselves but I don't think many people will use this feature because they feel that they are not free to use their money.
Even though there is no such feature, we should be responsible for playing gambling to know the limits and not violate them for our own good. In addition, gambling addiction can arise at any time; if we don't know how to prevent it, we can become the next victims.
I agree, even there are no additional features like this, better to be more responsible to avoid losing a lot and especially to avoid getting addicted, I'll go with your statement that those who are not comfortable using the limitations will feel that they are not practicing their freedom when playing.
Most gamblers are being attached when they are free to do things. When they are in sessions, win or lose, they've got the satisfactions
that they've aimed before playing/gambling.
We don't need this feature if we are responsible on what we are doing, maybe gamblers who cannot control theirselves just finding this because maybe they want to blame the casino for not having this feature that's why they exceed on their own bet limits. If they could just handle excessive things and can take better decisions for sure they will not ask about limits of anything on a casino.
