If it was up to me a concrete condition of any deal involving public tax monies being used to finance a stadium for a private entity would be the taxing authority gets full access to the private entities financials so long as they lease the stadium/repay the loan.
Another factor is what the little voice in a player's head called " agent" is telling them about a career transition from starter to reliever early in their MiLB-MLB journey.
I'd much prefer buying tickets to see if the young players can find their way or flame out at the MLB level then buy tickets to see Margot-DeScalf level MLB veterans play.
