If I was that couple, and already had all household things I needed or had room for, I would try and get the word out that we had plenty of stuff, because I know its tacky to say no gifts, and I dont think Ive ever been invited to a wedding that mentioned no gifts.
If you can’t afford a splashy honeymoon, you don’t book one, if you can’t afford the catering per plate for a large wedding, you adjust venue and guest list until you can. Expecting others to pay for your personal needs because you do not yet have the means for the lifestyle to which you want to become accustomed is not my concern.
You can certainly * accept* cash, if someone really wants to give it to you, but don’t ask for it.
I am currently however, contributing to a gofundme for a local artist, whose dog ( an 8yr old australian sheperd), apparently got into poison, or ate a poisoned animal, and is deathly ill.

I have been following his career with great interest, as he is very talented, but also has been struggling with homelessness and schizophrenia over the years, although he seems to be doing much better lately, and I expect his dog provides a great deal of support.
But outside of crisis situations, I don’t hand out money. Having to drive to Yosemite, instead of fly to Cancun, isn’t a crisis.
