A logbook entry is not going to hold the aircraft together, nuts and bolts do that, regardless of bits of paper.
Of course not. However, a proper logbook entry is a record that the work required for the aircraft to be safe was performed, and by whom. The work required for the aircraft to be safe is a minimum for the aircraft to hold together.
Yes, I have flown some pretty scary looking damaged aircraft home from the bush for full repair. But, I did it after the required inspection, and with a flight permit. And the destination was not furthering a recreational trip, it was to a suitable repair facility.
Yes, guts and duct tape, but to get out the best you can, not to thumb your nose to safe flying practice, and continue outward on a trip of fancy.
