Para-amino salicylic acid (PAS) was the first effective anti-tubercular, and was on the market prior to streptomycin. PAS, which is still used occasionally, can have terrible GI side effects (it is, after all, an aspirin derivative) and streptomycin will make you deaf and in a permanent state of vertigo if you take it long enough. Dihydrostreptomycin, which is used now, is a little better but not all that much.
Collapsing lungs, etc. did nothing for people whose tuberculosis struck in other organs.
