I understand what you guys are saying, and I personally agree that a cash game with actual cash is the preferred way (for me) to host a poker game. But you have to take his posts into the context of this thread, which is specifically discussing how to run a cashless game. It's great to personally want to play cash only, but it makes no sense to come into this thread and disregard the issues that make cashless desirable to those who do play this way.
What you are missing is that once they've made the decision to do cashless, they feel like they need to reduce the total numbers of transactions, and make the ones they do have not look like they are hosting a poker game. If, as you guys would prefer (I assume) all buy-ins and rebuys go to one person (host or predetermined banker) and then later that same person distributes those payments in a relatively similar total, but in different individual amounts, back to the same group of people, it would be pretty easy for anyone on the platform reviewing these transactions to guess the these individuals are gambling. Which is against their policies, I believe. So the purpose of the losers paying the winners after the fact is to make the transactions look like more traditional "friends sending friends money" transactions.
