To clarify, I also have a straightforward bank savings account emergency fund in addition to the Roth.
Roth withdrawals would not be my first choice if I needed cash. This is because, as you mention, the retirement investments in your Roth may take losses so you end up with less available than you thought and, also because the maximum annual deposit means you may not be able to put your withdrawals back, so there is an additional long-term opportunity cost. That said, to me, the option to make tax and penalty free withdrawals of principle, should the need arise, is worth a lot in the case of a major health/employment or other crisis, which are not crazy black swan scenarios.
This discussion and related reading has me softening a bit about extra contributions to 401k's. I would just caution that while there are ways to get at that money before retirement, they are highly constrained. If you remain employed, they are also subject to approval by your plan's administrator -- it's not enough to decide for yourself that you are willing to pay penalties. If you think you might need that money, don't just lock it up with the hazy sense that it will be available if you need it.
Edit: Not investing in retirement accounts out of a hazy fear of needing the money early is also a mistake, of course.
Edit2: So, I guess my personal order would be something like:
1. The not paycheck to paycheck fund covering ordinary emergencies like car repairs
2. Contribute to your 401k up to any company match
3. Pay off any debts with interest rates ~5% or more above the 10-year Treasury note yield.
4. Emergency fund
5. Some but probably not max HSA (if applicable)
6. Max Traditional IRA or Roth (or backdoor Roth) based on income level
7. A larger emergency fund
8. Extra but probably not max 401k
9. Pay off any debts with interest rates ~3% or more above the 10-year Treasury note yield.
10. Some split of 401k and taxable account with any extra.
