>> Over 220v, electricity becomes an extreme safety issue. You don’t just double voltage in a family setting. Ditto for increasing current (an issue with fast-charging capacitors). <<

So maybe Tesla needs to design a compartmentalized battery? Sorry if this is really silly, but:

If this is 110 volts,

why can’t you do this?

and get 440 volts?

440 volts is not four 110 volts in parallel. You’re confusing current with voltage.

Let’s put my concern this way:
Would you rather be dropped on your head onto concrete from 110 inches, or from 440 inches?
For safety, let’s add a mattress in the landing zone. The 110 inches now looks survivable. That 440 inches looking any better?
Now, in this context your suggestion is like being dropped 110 inches four times.

Put another way, you’re mixing up the difference between X*4 vs. X^4. (Being a bit-pusher, my electrical equations are rusty so I won’t go further.)
