No. The Lakers have destroyed their team for 6-8 years. They have a one and possibly two year window to win and they will need to get a number of lucky breaks to get what they need to do it. Given the absurdity of the Lakers ultimate package, I wonder why this is even up for debate.
Difference between the Celtics and the Lakers is that they didn't have many assets (mainly by giving up Russell, Randle, Bryant and Zubac for basically nothing). So in order to come up with an overwhelming package the Lakers had to take a huge risk by giving up most of their young talent and future picks.
The Celtics on the other hand had a so-called 'warchest' of assets. Big collection of draft picks and highly rated talent.
Perhaps even more important is that the Celtics had established players as well, so some young guys were kind of expendable.
Even if Ainge had offered a massive package of:
Tatum + Smart + R.Williams + #14 + #20 + Memphis pick (and I agree it's kind of absurd, since it would have been the best package ever), the Celtics still wouldn't have crippled their roster as much as the Lakers.
(I would have tried to get the Pelicans to take Rozier instead of Smart, but ok)The Celtics would still (potentially) have PG: Kyrie Irving / Terry Rozier(?) / Brad Wanamaker
SG: Jaylen Brown / MLE player / PJ Dozier
SF: Gordon Hayward / Marcus Morris / Semi Ojeleye
PF: Al Horford / Grant Williams / Guerschon Yabusele
C: Anthony Davis / Aron Baynes / Daniel Theis
Very expensive roster, but a real shot at a championship.
