Enough to provide enough mining security to be robust to attack from a state-level actor.
How much is that?
Go and check hashrates of BCH, BSV, LTC, DOGE, etc.
The game theory on bitcoin is that the miners will adapt, the ones who cannot operate with the margins of each epoch, will left the network allowing the ones who stay to make more money.

Nobody knows how much it is. That's the point. And if you're drawing your comps for btc's desired security budget from a bunch of shitcoins, I don't know what to tell you.
Game theory isn't magic -- all of these parameters are bound together to produce the complex system that emerges. You can't solve it in closed form and predict what will happen.

If nobody knows why you think is needed? who will impose this variable?
I gave you an example of shitcoins to make you think.
