If the results are good in the UK you can bet they will implement it elsewhere. It's not that bad, especially when considering that if the gambler loses a lot the government will have to give them social benefits.
Perhaps on countries where social benefits are really good for those with low wages and no work, they might see/feel the need to implement a similar regulation so as to reduce the number of people falling into the debt oblivion. But for real, the general population that gambles contribute to the economy by just losing there alone, and even online gambling opens up jobs for other people especially in these times when one cannot simply visit a gambling house. Why the need for such strict regulations and not something that could help the scene grow?
I don't know if letting the gambling industry grow as a whole will benefit the population. The way I see it, they want to allow gambling so that the gambling industry can be controlled and parts of their revenue goes back to the government. But not free enough so that the population do not develop massive gambling addictions (which are bad for the society as a whole).
