Post real world data to support that.
I don’t have a Tesla, I have Chevy Volt. 105,000 miles in with no range loss. According to GM, Gen2 Volt gets 6,000 charging cycles before “noticeable” range loss. That’s 16 years of daily charging.

The lithium-ion battery capacity degrades with every cycle, or every full charge and discharge, explains
Driving Electric. The good news is that this decrease in battery function happens gradually and should not be noticeable until your vehicle has aged.
Like a regular car battery, similar factors can impact the lifespan and performance of an EV battery. Hot outdoor temperatures or even overheating inside the battery can cause early degradation. Freezing cold temperatures can also slow down the chemical reactions within the battery, preventing it from reaching a full charge. Regularly draining the battery down to 5-10% will also cause it to wear out faster.
Even though electric batteries degrade over time, this can range from as little as
10% to 40% over the vehicle manufacturer’s warranty period according to Green Car Reports. The most common warranty ensures that your EV battery should function at 70% capacity after 100,000 miles or eight years.

I typically get over 300,000 miles out of a car.
But with an EV that would take a 2nd set of batteries, at about an additional $10,000 cost.
With wipers, heater, and headlights on, the typical 300 mile EV range also is reduced to less than 130 miles.
