We don't make buildings from Lego blocks. We do use modular components on buildings (ceramic bricks, steel beams, etc), but they are cemented or soldered together into a monolithic whole.

In my opinion, "serverless" (which, as others have noted, is an horrible misnomer since the server still exists; true "serverless" software would run code exclusively on the client, like desktop software of old) suffers from the same issue as "remote procedure call" style distributed software from back when that was the fashion: introducing the network in place of a simple synchronous in-process call also introduces several extra failure modes.
