Chairs are easily moved. Filing cabinets, however, can be tricky to move sometimes. If you have one on top of another shooting it will cause it to move towards you. Never the less, it is possible to blast them out of the way. Even if it was impossible to move filing cabinets, it is impossible to block all hostage rescue routes with filing cabinets. When Tempus says the point is moot he is telling the truth. Hostages can push chairs and filing cabinets aside and walk through barricades. If you can get into the room then you should have no problem getting out. If there is a barricade that a hostage cannot get through then I have not seen it. If such a thing is possible to create then it would still be very simple to knock it down.

The Counter Terrorist team has many options when entering a room. Smoke, flash, and HE grenades, and the different entrances allowing for simultaneous entry are very powerful tools. In all of the games I've played on office, the barricades were simply a tool to slow down CT entry and to give away their position. The idea of using barricades to block hostages in a room is ridiculous.

I don't think this tactic is "cheesy" or "cheap" at all. It takes more effort for the Terrorists to set them as it takes the CTs to unset them. It is about as cheap and as cheesy as a flash grenade. It is realistic and beatable. Banning or restricting such actions will only remove an interesting element from the game and further limit the options available to the defensive team for the benefit of an unrealistic and unlikely scenario.

Also, how does this promote "Death Matching" anyway? If it was possible to make the hostages unable to be rescued then I would understand, but it isn't. It makes it more difficult, which is exactly what an objective oriented defensive team should aim to do.

I am obviously in favor of not making any rules regarding this tactic. I think there is much to lose and little to gain by doing so.
