France didn't want Louisiana back at that time. Until Napoléon took over it was not a concern for the government (and he lost interest in it pretty soon, too).

Basically Louisiana would be a bread basket (and pork & beef basket?) for Caribbean plantations. I don't know why an earlier French government could not come up with a similar plan.
