You can if you don't want to keep track of a single adapter. I personally have two, one for the car and one for everywhere else.
You can blame Apple for using lightning if you have problems with non universal, non proprietary standards. USB C is both universal and non proprietary. It's even capable of sending analog audio exactly like the 3.5mm port does so you don't need an adapter with a DAC in it, just a USB C -> whatever you want to plug your phone into cable.
That said, most phones (including my Pixel 2) don't support that feature and require an external DAC in the adapter. I only bring it up because many people don't seem to realize that USB C is capable of doing anything the 3.5mm port can do.
>Headphone jacks work. They work really well. There's nothing wrong with them, and they don’t need replacement.
The PS/2 ports worked for your mouse and keyboard. They did have some issues but I would be okay with saying that they worked really well. They didn't need to be replaced with USB. They were replaced with USB anyways. That's the whole point of USB. It's universal. As long as USB is capable of transmitting audio then there is no reason to keep the 3.5mm port around. It's redundant.
