Acts is fiction (likely based on the epistles and Josephus). There are 7 undisputed Pauline epistles (though a few scholars even believe none of them are real - most recently Nina Livesey). So his itinerary certainly wasn't as vast as depicted here (also, it's impossible). Itinerant preachers were supported by communities they preached to. Also, Paul is urging people to give money to his 'collection for the saints'. There is no word what happened to it (neither in Acts). Hmm...

There’s nothing in Acts that could be said to come from Josephus, what do you mean? Josephus does not mention Paul at all and has only a brief disputed reference to Jesus.

What I meant is that the author of Acts "borrows" themes from Josephus to create his story. You can check out this interview with prof. Steve Mason: https://www.youtube.com/watch?v=wvfPxFQCpCU

Sometimes “themes” are just history repeating. There’s no evidence of this.

The timeline is also problematic because it’s entirely possible Acts was written first. Indeed IMO an earlier dating of Acts is pretty likely, the story is abruptly terminated after Paul has been in Rome two years with no natural conclusion, suggesting the narrative ended there because that took the author up to current events (60), where Josephus obviously wrote much later.
