Flipping the argument around: if the labour capital you earn today will be worth just as much as if you earn it tomorrow, why go the extra mile now, when you may just as well postpone it?
You are aware that just makes my point even stronger, right? Thanks to inflation, the labour capital I earn today is worth even less than the same capital earned tomorrow.
Inflation is by design. Currency derives from current, meaning: to flow. Currency is not meant to be a store of value. We don't want people to horde currency.
Bitcoin just misses the point of being a currency all together.
