I think you need to consider the timeline. Late march, throngs welcomed Jesus to Jerusalem riding on a donkey. 3 days later, everyone ran away and there were only three people by the cross, and one of those was His mother. Three days later, talk of resurrection starts growing and is known to everyone in Jerusalem. For 50 days nobody hears any more, and then suddenly, end of May, there's a 120 friends and relatives praying in an upper room in tongues (whatever that is they had never heard before), and 3000 people get saved. Within weeks, 12 ex-fishermen, zealots and tax collectors are running a community of maybe 5000 converts, a job for which they have no formal credentials, and it's working. We know this thing lasted less than 8 months, because we are told by early writings that Paul started his ministry a year ater the ascension (May), and we can work backwards. Sometime by August or so, many of the 5000 people said, "let's do like the folks at Qumran. Let's sell everything and buy property together, so we can study about Jesus". So, the 12 guys, already burdened by having to set up deacons because of arguments over food, take the money, buy the property, and start feeding the people, who now have no resources left. They all pledge each other everything, all their life savings, all their futures. Just like the people today who think Jesus is coming back in June or whenever sometimes do. And it's getting worse; the pharisees are angry, and the weight of the Temple government is starting to threaten. Now here's a couple that want to join up. They say "here's all my money, let me live with you and off the common purse. Give us the same voting rights, and authority you all have, because our lives are now yours so we can follow Jesus." They said to God, and to several thousand people, "we are 100% with you, and have given up the right to walk away. We will have no backup plan for when the Temple sends the Roman army in. If we die, we die with you in the name of Jesus." But they hid some money. They were ready to run; they were not committed. This was not a time for cowards.
