In as much as the end goal is to tackle excessive gambling and addiction, i don't think it is necessary for the government to interfere by setting a loss limit for gamblers. Let's not forget that the people involve in gambling are both the rich, average and poor. Of course, the loss limit might actually be a big deal for some people, especially those below average, but those who live above average might not have any problem with it. Seeing how much was imposed by the Finland government, i think it is a decent amount, but at the same time, it won't sit well with others especially those that have more than enough to risk.

Should this is be good deterrent to at least minimized gambling in a certain country? Or does it force gamblers to uses illegal means or even travel outside of the country that has this strict law to continue with their gambling?
Of course, people are either going to outsmart the system, or seek for other options like travelling out of the country.
A lot of people can do crazy things just for fun.
