Guess you could put that all on a clip to a belt? There really isn't much you can do to avoid carrying the bulk.

Keywallets, little leather pouches that all the keys to swing out

This is not true these days

Wireless mice have such low latency these days that eSports pros will use them in competitions where million$ are on the line.

I feel like the solution here is to go wireless

Most wireless mice have a detachable cable and work wired. So even once the internal battery dies, you can just use it wired forever

But bewarned if this mouse is used for gaming, no mouse is buy it for life. They have moving parts that wear down, even stuff you don't think about like the mouse feet wear down. I'd suggest jyst buying cheaper mice with the expectation they last 5 to 10 years.

I am very familiar with the framework laptop

I just don't think laptops go obsolete fast enough that this is the laptop for most people.

Electronics, specifically microchips, are not BIFL just by their own nature. I love my electronics but I don't expect them to last forever, it's not realistic. A good laptop is going to last 6 to 10 years anyways, really depends on how much and what you use it for. And by that time pretty much everything in it will be ourdated and you probably want a new one in general just so it'll look newer.

Plus they aren't that expensive either! Compared to something like Bed Bath & Beyond they are like 1/3 of the price

The Charisma towels from Costco are pretty damn good. They don't seem that fluffy in store, but wash them once and twice and they transform into really good towels (says something on the tag about this)
