Well said!
I've been executor for various family members of my own and DH, and we've also suffered with parents with long term health issues, dementia, etc., and it's an absolute nightmare when they've not made any preparations at all, not just no wills or POAs, but not even paying household bills out of a joint account, which is really the bare minimum for making things easier.
I've also been involved when clients have died and I've had to sort out the mess of paperwork to try to put things together and work out what's happened with finances and get an angle on what they've got upon death. It's often an absolute nightmare.
Because of that DH and myself have streamlined everything, got joint accounts in place with direct debits set up for as much as possible, disposed of old obscure investments, streamlined savings and investments, etc., plus all POAs and wills, and even organised all our personal and household financial paperwork.
Even drafted our inheritance tax returns, with current values for bank accounts, savings, investments, house, cars, chattels, etc., and including lists of declarable "gifts" during the last 7 years, so all it needs is updating every couple of years (quick and easy job for us), and our DS will be good to go and not have to spend hours/days trawling through the house trying to track and find finances, assets, gifts, etc.
