Because all my light switches are Wi-Fi connected, how would I remove my traditional light switches but still have easy access to turning on and off those wires so I don't always have to go to the breaker box?
You can’t and don’t want to.
First the “can’t” reason for the United States: While not every light and switch in residential dwelling units is considered required lighting, at least one light and switch in every room is required lighting and must have a switch at the door in the US to follow the National Electrical Code.
Lighting outlets in dwelling units must be installed in accordance with 210.70(A)(1), (2) and (3). At least one wall-switch-controlled lighting outlet must be installed in every habitable room (and bathroom) of a dwelling [210.70(A)(1)]. This provision requires at least one lighting outlet in every habitable room and at least one wall switch to control it. The dictionary defines habitable as “fit to be lived in.” Habitable rooms include, but are not limited to: kitchens, breakfast areas, dining rooms, family rooms, great rooms, bonus rooms, sitting rooms, living rooms, parlors, libraries, dens, sunrooms, bedrooms, recreational rooms, etc. Unless meeting one of the two exceptions, at least one lighting outlet controlled by a wall switch is required in every habitable room.
You also “don’t want to” because you need that backup switch. What happens when for whatever reason WiFi switching isn’t working? In my home the only two standard light switches exist, both control garbage disposals, it’s not very often but occasionally things fail and the light need to be turned on or off easily. If the WiFi switch is tucked away in the basement/closet or inside the light fixture then there is no way to just go to bed and fix it tomorrow, or go to work and fix it later, or maybe your internet provider can’t restore service until next Tuesday... etc etc...
Finally, while you think the WiFi switching system you’ve created is all anyone would ever want, removing wall switches will negatively affect resale value. While many of us embrace such automation most of the world isn’t ready for it yet.
There are plasctic switch covers you can put on over your traditional switch. They are covered in the front to prevent accidental toggles, but open on one side so you have access if you need it. I have several on switches that I've put smart bulbs on.
