You're missing the point. The POINT is that you're supposed to do whatever it takes to win, and complaining about a legitimate mechanic is nothing more than whining. These combos also aren't infinite; you can only jab lock someone three times, so most jsb lock combos don't even lead to death. They also don't happen that often, as smart players know how to avoid situations of being put into them.

Basically what I'm saying is adapt. It's not cheap at all.

You can't be serious…

Well, fuck, why don't we just take out hitstun, then? Why don't we ban edgeguarding, as well? Hell, why don't we make KOs impossible while we're at it?
