Multiple problems with this one.
For one, acquiring an instrument is expensive - even secondhand, most instruments cost a significant amount of money. Learning it properly is even more important and expensive - fixing something in a DAW is easy, unlearning muscle memory is much harder.
Keeping up said muscle memory also isn't easy. Sure, if you got a free-standing house, no one will care much about a drum set, trumpet or whatever. But most people don't have that luxury in urban sets any more, and typical residential building quality makes even some electronic instruments (e.g. kicks still cause some amount of noise passing through floors) a challenge. Building noise ordnances / HOA rules are a bitch on top of that - most allow only a limited time window in the afternoon, useless for working-class people.
Local community groups... if your community has one, and they have some studio space where noise doesn't matter, great! Most, unfortunately, don't - space in urban environments is already rare and at a hefty premium, space that accepts noise and has adequate resources (in practice: a usable toilet is the most important) is even rarer.

You can find really affordable used guitars or keyboards which are completely suitable for beginners. Beginner's electric drum kits are cheaper than real ones and hook up to headphones - there goes your sound problems.
I definitely agree it is much harder to learn a instrument than it is to learn a DAW. Believe me, I've done both.
There are lots of reasons to forego picking up an instrument, but living in an apartment or a modest budget are certainly not good reasons.
Go check out a drum circle, all you need is a bucket. Learn to sing, join a choir. It’s not that hard if you quit making excuses. I’ve lived in small towns in rural areas for most of my life and there have been multiple community music groups in all of them.

This isn't true at all. You can get a brand new Squier Strat for < $200 and a second hand one for less than half that. You can pick up used acoustic guitars for next to nothing if you look hard enough. You can get a used digital piano for < $200 too.

Depends on the instrument. You can get a completely new Harley Benton electric guitar for sub-$200.

Sure, trumpets and classical instruments are a challenge, but all the guitars and all the keys can be practiced on headphones with near-zero noise. It's not an excuse.
