Is a funeral without a wake a bad thing?

‌Is it a bad thing to quietly send off the deceased with only immediate family members because finances are tight, immediate cash flow is difficult, and I don't want to cause any inconvenience to those around me?
People say things like, "That's not proper," or "You absolutely must receive mourners."
It's like when people say, "I can't afford English kindergarten for my child because my salary is low, but you should send them anyway because people will talk or gossip."
I am planning to hold a funeral without a wake due to my personal circumstances, but if I can't even do that because I'm afraid of what others might think, it's just exhausting. It is a matter for the person involved to handle according to their own situation; why do others feel the need to comment?
