So if the situation came, where the plane was at the edge of its flight envelope and needed to use MCAS (or whatever its called now), it wouldn't have been able to use it, causing the plane to stall? Thats a lot more serious then.

The plane doesn't really NEED to use MCAS. Systems like MCAS or Speed Trim and others do not make the planes flyable, they make them predictable. Aerodynamically, even the 747 or the A380 are normal planes operating on the same principles as the tiny Cessna 172, they're just much bigger, fly faster and react a lot slower.

Airliners are packed with systems that make them dull and predictable to fly, because things can break on a sunny day over Texas, but also at midnight in the rain over the Atlantic, and the last thing you want your pilots to care about when they're stressed out, disoriented and working through complicated checklists is whether this particular plane has a weird tendency to pitch up at these particular conditions.

Nope. “The EASA flight tests confirmed that MCAS was needed to provide full compliance but also that the loss of this function does not preclude the safe flight and landing of the aircraft; i.e. the 737 MAX remains stable following the loss of the MCAS function.”
