The review that was set up in the wake of the ball tampering incident had observed that Australia's players were living in a "gilded bubble - disconnected, for much of each year, from families, friends and the grounding influence of community".
Skipper Smith and his deputy Warner were slapped with a one-year worldwide ban while rookie Bancroft was suspended for nine months by Cricket Australia in March this year.
Longstaff pointed to Australia's sledging culture as further evidence of the systemic faults in CA's approach.
The review found that CA was partly to blame, and viewed more widely as "arrogant and controlling". "The core complaint is that the organisation does not respect anyone other than its own".
He said: 'I think they should be back but it's up to the board to make that decision, not me.
Former Cricket Australia chief executive James Sutherland who stepped down in June after a hard period for the sport.
"They have to be responsible for their actions, regardless of what is going on in the background with the administrators and the culture that's been created". They revert to bully tactics or worse, ostracising!
The board rejected a recommendation that Australia's elite players stop playing worldwide Twenty20 cricket.
"Australian cricket has lost its balance. and has stumbled badly".
But former Australian bowler Geoff Lawson said the chairman should be replaced by someone who played at the elite level. Women's cricket remains unaffected.

Bans imposed on Warner, Smith and Bancroft for their role in the Newlands ball-tampering scandal should be re-examined in light of systemic failings raised by the independent reviews into CA, the players union president Greg Dyer said.

Longstaff has recommended a cricketing ethics commission be established, comprising three persons, nominated by CA but rubber-stamped by the states, the Australian Cricketers Association and Cricket Umpires Australia.
Symonds also declared that the Australian team lacked real leaders, something that had been a problem for years.
Tim Paine, who succeeded Smith as Test captain, said the players had adjusted their priorities. This may involve mediation.
The report also recommends changes to the role of co-captain, which it terms as being that of an "heir apparent" to the captaincy.
Speed wants former national captain Mark Taylor to take over from Peever as CA chairman.
Ironically, the review's most urgent recommendation was for CA and the ACA to establish a constructive working relationship within 30 days.
"I know all involved, would have preferred that the events in South Africa didn't occur", Peever added.
The third player suspended, Cameron Bancroft has another two months of his nine month ban still to serve. Howard had been criticised for his involvement.
CA chairman David Peever on Monday rejected the possibility of reducing the bans, saying after releasing the review findings that "the sanctions were imposed by the board after a very full and thoughtful process and so the sanctions stand, as I said several weeks ago".
