Would you be willing to shoulder all of that at your own expense in time and money? Of course not. You can't expect people to put so much energy and so many resources into something like that and just eat the costs. That's why a rake or seat charge is necessary to have a game that regularly. This is not to even mention the time of the hosts and dealers, who would be essentially running the game as a full-time job. The reason there are practically no daily or near-daily unraked games is that it costs money, as well as assumption of financial and possibly legal risks, to run such a game.
