Why would we want a deflationary currency as our day to day currency?

Wouldn’t it only benefit those who already have substantial savings? Wouldn’t it encourage those who have savings to not spend their money slowing down the economy? Wouldn’t it further disadvantage those who don’t already have a home or anything paid periodically, since loans interest would have to be higher (why would I lend someone money at a lower interest rates then the natural growth of the currency) and the value of of that loan would further grow with time making it harder and harder to pay? I searched for answers online but I mostly found people saying inflation is a hidden tax, but I think is a good tax, tax are obligatory for a functioning society and a tax that majority affect only those who are more economically stable and secure while stimulating the economy I think is the best solution rather then further making rich richer and poor poorer
