You are confusing the impact of thrust at launch with that of lift.
If you don't have enough thrust at launch, you add lift, increasing wing surface or augmenting the lift force by flaps, LEF, angle of attack etc...
On the contrary, a fighter jet designed with performance in mind will be limited first by the thrust available in dynamic conditions (Flight maneuver, Acceleration, altitude... ). There the impact of lift augmentation devices being drastically diminished by the g number (divided by two, three... 9 in a matter of seconds). Thrust becoming the lead parameters.
Carrier launch and arresting design are only a fraction of the limitation an aircraft must meet. See how Naval fighters happens to outperform their land based rivals from time to time.

Then there is the cost. French MoD has certainly a good projection of Dassault aircraft cost by weight. Even factoring-in the impact of the diminishing parts count, they are probably able to make good projection of the maintenance cost.
And we all know that's not the good aspect of Dassault and Airbus designs. Hence see this reported limitation as a fairly prudent requirement to keep the project alive and perform.

Also, being rational, 16t is 60% higher than Rafale empty weight. It seems compatible with what we are given to see.

Nope. The catapult provides most of the thrust... that’s the whole point otherwise people would just use ski jumps.

The aircraft provides the lift, and only needs to provide enough thrust to continue accelerating once in the air… which for a fighter is never an issue.
 
45t at 130 knots translates to 35t at 147kts (simple energy conversion formula E=MC2).
E=MC² is the formula for complete conversion of mass to energy, with C the speed of light.
The formula for the energy needed E to accelerate a mass M to a speed V would be E=½MV².
The speed for mass results are the same for that catapult, though :)
 
Theoretically correct, though. At the fraction of light speed we are currently able to reach with most anything heavier than elementary and composite particles - with great big accelerators - in nearly all cases the difference is negligible between matter at rest and matter in motion.
