I am aware that the competition in the industry is good, but more casinos mean more publicity for gambling, and more publicity for gambling means more gamblers definitely, and if there are more gamblers, we will have a higher chance of people who will turn up with a gambling problem or challenge.
I like the competition because it would encourage existing casinos to find ways to serve their clients better in order to retain them.
More casinos poses a problem of identifying good ones from scam. Some bad actors might take that opportunity to defraud people
New casinos doesn't necessarily mean new gamblers, trust me, the influx of gamblers outnumbers the casinos more than a thousand to one. If you go into the streets and see the way even little children frequent physical betting houses, you'll be amazed, not to mention what is happening online.
