Totally tanking from the pre-season forward through the entire year is fine?
This is not tanking,
With contract years you want to max your best players windows. Taking Lacy off now and wasting a year when you can't win is foolish. Leaving him on the taxi is good roster management and planning
It's a bad rule that needs to be changed. It isn't "tanking" within the letter of the law of the rules but it surely is within the spirit.
It's also a loophole that the team that just acquired Lacy can place him there if he was activated by his former owner last year.
This. A player used in a fantasy game should be ineligible for ANY fantasy taxi squad.
as long as the owners come to an agreement and the rule is consistent, there's no problem with this rule or one that allows you to put a 2nd year player on the TS who you used last year. If an owner called up Knile Davis or Edwin Baker up for the end of 2013, some leagues would allow the 2nd year player to be put back on the Taxi Squad for 2014. I have no issue with this rule; my only league with a TS has this rule and it seems to work fine.
As for tanking, while this is just one writer's opinion, it makes sense to me:

"Tanking," as we are to understand it, is a team's intent to do less than everything it can to win.
While tanking is a mechanism usually employed with regards to the draft, the most egregious example of deliberate losing in recent history perversely had nothing to do with it. An April 2006 game between the Minnesota Timberwolvesand the Memphis Grizzlies featured an overtime win for the Grizzlies that they simply did not want. They were unable to play worse than the Timberwolves, who unashamedly let Mark Madsen shoot seven three pointers in a bid to have one of the 10 worst records in the league, thereby keeping a conditional pick they owed to the Clippers.
Understand this was a tangent, but it's one worth discussing IMO.
The problem is that you cannot so narrowly define "trying to win" in dynasty. Trying to win what? A single game? This year's championship? All the championships ever?
Let's say you were in a league last year that had a positional maximum of 6 WRs, and you had Calvin, Julio, Harvin, and Crabtree. When Calvin's bye came around, what do you do? If you don't cut one of those four to add Brian Hartline, then you are demonstrating an "intent to do less than everything [you] can to win". By that definition, a refusal to cut Julio Jones for Brian Hartline is tanking.
Or a specific example that I dealt with last year. I had a team that was not going to make the playoffs. Jordan Reed was on my Taxi Squad, and he was outscoring the player I was starting in my flex (Tyler Eifert). The league's rules, though, stated that Taxi Squads were set before the season and once a player was removed he could never be added back. The league in question had shallow benches, and most of my bench was already devoted to carrying injured players and non-contributors (Julio, Harvin, Crabtree, Hunter, Eifert, Gronkowski, etc). I was faced with an option- activating Jordan Reed would improve my weekly scores, but it would also cost me one of my precious few roster spots on a team that already barely had enough room to field a weekly starting lineup. I chose not to activate Jordan Reed. Was that tanking? I would argue it was not- like cutting Julio Jones to add Brian Hartline, sacrificing a roster spot for a small scoring bump would be a short-sighted move that would hurt my team in the long run, even absent of draft considerations.
In my mind, the draft considerations are the key. Draft considerations are rewarded to bad teams, incentivizing teams to be bad for its own sake. That's exactly what was happening in the basketball example you linked to- teams were trying to be bad for its own sake because of draft considerations. If it were not for the draft considerations, neither team would have behaved like that- they would have had no reason to. If draft picks were handed out alphabetically instead of by order of finish, Memphis and Minnesota would both be trying their best to win that game. However, even absent any draft considerations, I still would not have activated Jordan Reed- the primary consideration in that decision was the roster spot, not the rookie pick. That's a decision that stood on its own merits, and the improved draft position was a happy byproduct.
That's the test- if draft picks were awarded alphabetically, would you still make that move? If no, then it's tanking. If yes, then it's not.
