In the spirit of furious agreement, yes the best option would obviously be not to suppress construction.
Just because one interest group wants stupid things to happen that benefit them in the short term doesn't make it a good idea to go open season on stupid things. The goal should always be to improve the state of affairs; not to spread the pain around.

It also follows from supply and demand. Owners are more likely to sell rather than rent out their places, and tenants are more likely to stay in their below-market rent units, both of which reduces supply for new (i.e. market-rate) tenants.
Visible benefits; invisible costs. Great politics.
Who you don't see are the people outside looking in that want an apartment but can't find one, or can't afford one, or need to sign a new lease at a very high rent.
Rent control doesn't unequivocally help current renters. It also keeps them stuck in one place for a long time, even when it's not a great fit for them.
And pretty much every economist says rent control raises rents and lowers quality overall, hurting those trying to move in.
