Justification for Loose Calls

[NYCNative]

Villain makes a lead bet on a flop where a call is -EV. When, if ever, do you make a loose call? I see several possible scenarios where you can do this:

1) You have enough chips where a loose call that doesn't hit won't hurt very much but if it hits, you will get paid off and/or knock villain out.

2) You feel that you can bluff and take the pot down even if you miss on the turn. (For example, you are drawing to a straight but a flush scare card hits.)

3) You are against a villain who will not fold that TP no matter what unless he is scared on the turn so a raise will not get villain to fold but a call followed by a scare card will. (I see a lot of such players at the lower levels.)

4) The draw is so juicy that you feel you have a good enough shot to hit it but that you can get paid off more when you do hit it than by raising here.

5) You feel villain will be scared by a smooth call enough that your chance of getting a free card on the river if the turn misses will be high.

Anything else? Or do all of these suck?
