First off rakebacks don't justify if a casino is a good choice or not. Personally I don't even see rakebacks as having a good enough psychological grip to actually strongly consider it with every single bet you take. If you consider the distribution of bets assuming wins and loses it not always worth it.
That aside most of the time the more you try to chase most of these bonuses the more you eventually lose more plus the rakebacks cannot mathematically cover your losses. Rakebacks add up in gross profit who luck puts you at an advantage.
Rakeback benefit is not a key factor in establishment of credibility of a gaming arena. This aspect is not psychologically potent to drastically distort the risk calculations of day to day activities because the amount of rakeback is always significantly less than what could be lost in terms of betting capital.
The addiction to earn the rakeback is in fact what causes one to bet more than they can afford. Intuitedly, with small rakeback percentage, it is not likely to counter down a losing streak, which proves the action of luck as the sole determinant of the ultimate profit.
