You literally couldn't go anywhere where you need a ramp to enter through and you basically can't go anywhere that doesn't have infrastructure like roads or paths so you're confined to cities or towns. Even moving throughout your own home can be a hassle where you have to clamber onto a chair when getting in and out of your bed as well as being overall less mobile especially in confined spaces like a hallway. Even something as simple as turning around is a hassle because you can just spin around you have to use your arms just to turn. Even if you're a hermit who doesn't leave your room you still make a lot of shit harder for you without your legs.
