HODL isn't bad things, but people must aware that if early bitcoiners don't spend their bitcoin and convince people to do same thing, i think Bitcoin price won't reach that far.
Obviously no one force you to spend your bitcoin, but i (and some people) spend bitcoin sometimes would help/convince more people to accept bitcoin (or at least keep accept bitcoin).
Also, bitcoin deflation model indirectly cause people to HODL. Personally, i think tiny inflation (0.1% or less) in bitcoin would be better and indirectly make HODL not too useful and make people spend their bitcoin even though majority community is disagree with my opinion.
I think you are confusing saving money and just straight up not be willing to spend any bitcoins you get your hands on.
There is absolutely no problem created by people saving their bitcoins whatsoever. It is just a more useful currency if people use it as well.
You can HODL all the bitcoins that you can afford, but gradually switch from using fiat in your everyday life to Bitcoin.
Savings and usage of the platform are not strictly related.
Saving bitcoins or any other currency doesn't really affect it in any negative way, it can only increase the price.
It is lack of use that could hurt it and if saving comes at the expense of that, then yes, but it really doesn't have to do anything with it.
This doesn't mean that you need to spend more bitcoins, this is a stupid idea.
This just means that you need to move your use of fiat to Bitcoin. that is all.
