Everyone that wants to honor his memory or pay respects to him can. Donate to something in his memory, contribute to making these boards better, do your ASMB get together in memory to him, everyone take a shot at midnight, write a wall of text in his memory, buy a star, etc, etc, etc...
Focusing on the physical details isn't important and judging his family or making assumptions that have no foundation is petty. It's not our business what his family chooses. For all anyone knows, luuv didn't want a funeral, obit, or anything extra. In any event, trying to pick apart his family's intentions, estranged or not, is something I'm sure he wouldn't want people doing. Leave his family to do what they need to and focus on how you need to remember and honor him in your own way or collectively as a board. That's all that matters.
In any case, RIP Luuv. Thanks for the good times and for reversing those bans in the old days. You'll always be a part of these boards and a part of all of our history.
