Why is the triple halving a good thing?

Just trying to wrap my head around it. I that that your lowering the supply and that demand will increase other time so they will help the price BUT isn’t the point of ethereum to spend it? Using smart contracts and building on Eth requires spending gas but if it’s more profitable to just hold it Eth becomes a store of value. Just trying to connect the dots, this seems to contradict what a smart contract platform would want
