Good morning!
Your bitcoin node is your vote, no matter what the miners decide, you decide what to write in the chain, bitcoin is like a living organism that replicates its cells, a node is a cell, the new cells will take their dna from the old cells, from your node, you decide which cells survive, you decide which cells will transmit their genetic material.
If the nodes do not decide to include a certain mined transaction, it does not survive, it does not replicate in eternity. Miners are obliged to follow the consensus, your node has more power than you think.
Bitcoin needs more nodes, it is the best way to protect your bitcoins.
