Earlier quoted context omitted.
Then don't get the dongle. Just upgrade your accessory to use USB type C. Having a bulky USB A port just to appease the 1% of users who spend $2000 on a shiny new macbook but cheap out on a mouse they've been using from the 90s? I exaggerate, but if you really want to keep your old accessories then leave the dongle permanently attached to the accessory. You can get like a 10 pack for like $5 probably.
It isn't really a matter of cost, so much as the inconvenience of replacing all the peripherals I've accumulated over time (ignoring the fact that there isn't even a USB-C version of my favorite keyboard). Yes adapters are possible, however an even better solution (in that it doesn't require remembering to bring an adapter everywhere) is just to buy a different brand of laptop.
I've found a single, compact USB-C hub does fine for me, but of course YMMV.
